What color is the water? In the eyes of westerners, good water is blue, such as Blue Danube and Blue Ocean. In the eyes of China people, good water is green, such as "white hair floating green water, red palm stirring green waves" and "green water and green mountains". In fact, pure water has no color. In the eyes of westerners, blue is the reflection of clear sky, while in the eyes of China, green is the reflection of surrounding vegetation. What color is the water? 192 1 in the summer of, an Indian scholar was bending over the deck to observe the sea surface with simple optical instruments on the passenger ship S.S.Narkunda sailing in the Mediterranean. He was fascinated by the deep blue of the sea water and was determined to investigate the source of the color of the sea water. This Indian scholar is Raman. He is on his way to Britain, representing the University of Calcutta, the highest institution in India, attending the Commonwealth University Conference in Oxford, and preparing to give a speech at the Royal Society. He was only 33 years old at this time. For Raman, the blue of the sea is not unusual. University of madras, where he goes to school, faces the Bay of Bengal, and he can see the changing colors of the sea every day. In fact, as early as 16 years old (1904), he was already familiar with the famous physicist Rui's explanation of blue sky by using the law that the intensity of scattered light in molecular scattering is inversely proportional to the fourth power of wavelength (also called Rayleigh's law). I don't know if it's because of my character of exploring the mysteries of nature, or because of my in-depth thinking of consulting literature when studying light scattering. He noticed that a passage of Rayleigh was debatable. Rayleigh said: "The blue of the deep sea is not the color of the sea, but the blue of the sky is reflected by the sea." Rayleigh's exposition of seawater blue has always been Raman's concern. He is determined to make a field trip. So, when Raman set out for England, he prepared a set of experimental devices in his luggage: several Nicole prisms, small telescopes, slits and even a grating. Both ends of the telescope are equipped with Nicole prisms as polarizers and analyzers, which can be used for experiments at any time. He used a Nicole prism to observe the reflected light of seawater along Brewster's angle, thus eliminating the blue light from the sky. The light seen in this way should be the color of the sea itself. So what you see from here is a deeper blue than the sky. He also used grating to analyze the color of seawater and found that the maximum value of seawater spectrum was bluer than the maximum value of sky spectrum. It can be seen that the color of seawater is not caused by the color of the sky, but an attribute of seawater itself. Raman believes that this must be due to the scattering of light by water molecules. He wrote two papers on the ship back home to discuss this phenomenon. These documents were sent to England during the stopover and published in two magazines in London.

What color is the water? Of course, water is a colorless and odorless transparent liquid!

But it is different to contain impurities.

There is also the influence of water on environmental color in other environments, all of which are visual effects!

Does not affect the water at all. It is colorless, odorless and transparent!

What color is the water in the five elements? The numbers represented by water in the five elements are 1 and 6, and the colors represented by water are black and dark.

Blue is wood, red is fire, yellow is earth, and white is gold.

What color is aqua pink? Visually, you can see the picture. Deep pink.

Color matching means white powder (not too white), add a little water, and a little refers to your white powder.

All the pink series can be matched with each other, and the lightness and purity are in harmony, but it depends on what hue you want in the end. If it's a cool tone, it's best to insert more cool tones.

What color is this lake? People can distinguish different colors because different colors of light enter people's eyes. The reason why the lake changes color is that with the increase of water depth, the light reflectivity of different wavelengths is different, and the light entering the eyes is also different.

The color of the lake refers to the transparency (take a white disc with a diameter of 25 cm and sink into the lake to watch it until it is out of sight. At this time, the sinking depth of the disc is 1/2, and the color of the lake displayed on the disc. Generally, it is expressed by water colorimeter 1 (light blue) to 2 1 (brown). A beautiful color of a lake (such as green) is formed by dissolving some minerals, and this color can only appear in a lake with high transparency. The color of the lake is also controlled by the water depth, because only when the water depth exceeds 5 meters, it is possible for the lake to absorb light from other chromatograms and only reflect blue light.

The most beautiful lake in China is also on the Qinghai-Tibet Plateau. The lakes on the Qinghai-Tibet Plateau are mostly turquoise and light blue (water color number 3-9). The water color of Yongcuo in Mabian is the clearest and blue. Qinghai lake is light blue; Ering Lake and Zhaling Lake are turquoise.

In Xinjiang and Inner Mongolia Plateau, Sailimu Lake in Xinjiang, Tianchi Lake in Inner Mongolia and Daihai Lake in Inner Mongolia are clear in color, and the lakes are dark green or light blue (No.5-9); The water in Bosten Lake is light green. Fuxian Lake is the clearest lake in Yunnan-Guizhou area, which is turquoise (No.5-No.8). Yangzonghai and Erhai are dark green (No.8-1 1).

What color is the water in the sea? Let me give you an example first. The water in the Bohai Sea in the west is turbid and slightly yellow. This is due to the natural phenomenon of submarine trench formation. Among them, the Yellow River estuary has brought a lot of sediment to the Bohai Sea, so it also has a certain influence on the color of the Bohai Sea. And it is determined by the salt content in seawater. There are many rivers in Bohai Bay, such as Haihe River, Liaohe River and Yellow River. So a lot of fresh water flows in, which makes the density of Bohai Sea lower than that of Yellow Sea. When crossing the boundary between the Yellow Sea and Bohai Sea by boat, there will be obvious sinking feeling.

Seawater is colorless and transparent like ordinary water. The color of the ocean is determined by the optical properties of seawater, the suspended solids contained in seawater, the depth of seawater, the characteristics of clouds and other factors. As we all know, sunlight is composed of seven colors: red, orange, yellow, green, cyan, blue and purple. The wavelengths of these seven colors are different. From red light to purple light, the wavelength gradually becomes shorter. Long wave has the strongest penetration ability and is easily absorbed by water molecules, while short wave has a weak penetration ability and is prone to reflection and scattering. The degree of absorption, reflection and scattering of light with different wavelengths by seawater is also different. Red light, orange light and yellow light with longer light waves are injected into seawater and gradually absorbed with the increase of ocean depth. Generally speaking, in the ocean where the water depth exceeds 100 meters, most of these three wavelengths can be absorbed by seawater, and the temperature of seawater can rise. However, blue light and purple light with shorter wavelength will have strong scattering and reflection when they meet pure seawater molecules, so the ocean people see will appear blue or dark blue. Due to the increase of suspended solids, the coastal seawater has larger particles, weak absorption of green light and strong scattering, mostly light blue or green.

Violet light has the shortest wavelength and the strongest reflection. Why is the sea not purple? Scientific experiments have proved that human eyes are biased to some extent. People's eyes are very insensitive to the purple light reflected by seawater, so they turn a blind eye. On the contrary, human eyes are sensitive to blue and green light.

Most of the ocean is blue. If there are too many suspended substances in seawater or other reasons, the color of the ocean is no longer blue. For example, the Yellow Sea in China was the mouth of the ancient Yellow River, and a large amount of sediment carried by the Yellow River flowed into the sea, which made the blue sea water "yellow". Although the Yellow River is now pouring into the Bohai Sea, the northern part of the Yellow Sea is connected with the Bohai Sea through the Bohai Strait, and it has to bear the river water injected by the Huaihe River and Guanhe River, so the sea surface is still pale yellow.

In the northwest of the Indian Ocean, the Red Sea between Asia and Africa has the highest water temperature in the world. A reddish-brown seaweed grows in the sea. Because this kind of algae grows vigorously all year round, it dyes the sea surface red, so the Red Sea is named.

In the Gulf of California in the northeast of the Pacific Ocean, there are blood-red algae communities in the south and a lot of red soil brought by the rainy season of the Colorado River in the north. The seawater is reddish brown, which is called Zhu Hai.

The White Sea is the marginal sea of the Arctic Ocean, which goes deep into the northwest inland of Russia, and the Arctic Circle passes through the White Sea. White sea is named "White Sea" because of its high latitude, cold climate, boundless ice and snow and low organic matter content. The seawater is white.

Fresh water such as Don River, Dnieper River and Doe River is injected into the surface of the Black Sea with low density. The deep layer of the Black Sea is high salt water from the Mediterranean Sea, with high density. Density thermocline is formed between the upper and lower seawater, which seriously hinders the water exchange between the upper and lower water layers. The Black Sea exchanges water with the Mediterranean Sea through the Bosporus Strait and the Da Daniil Strait. Because the strait is narrow and shallow, it greatly limits the water exchange between the Black Sea and the Mediterranean Sea. There is no oxygen in the depths of the Black Sea, and the sewage and corpses secreted by organisms in the upper seawater sink into the depths to rot and stink, and a large amount of sludge and turbid water make the ocean dark. In addition, the Black Sea region is often rainy and stormy, which adds a black feeling.

Red tides can also make the color of seawater abnormal. Red tide is a phenomenon that plankton suddenly multiply and gather together in local waters. The colors of red tide are varied, mainly depending on what kind of marine plankton causes it. The red tide caused by noctiluca is pink or brick red, some dinoflagellates are green or brown, and some diatoms are brown or reddish brown.

In addition, because the sun sometimes disappears in the clouds and sometimes shines through the clouds, the color of the ocean changes accordingly. The color of the ocean also depends on the height of the sun from the horizon.

People who are confined to artistic abstract thinking often think that the sea is blue, but in fact it is colorless and transparent, just because the internal factors and external environmental factors of the sea are different. & gt

Different experts have different answers to the question of what color water is at different times. From a physical point of view, the color of water is influenced by light source, absorption and scattering of light in water, suspended matter in water and other factors. The main light source of the earth is the sun, which has many colors, from the longest red light to the shortest purple light. The color of an object depends on what color light it emits. Water absorbs more red light, but scatters more blue light, but this phenomenon is only obvious when there is water with a certain depth or thickness (more than one meter). Therefore, in daily life, the pure water in the colorless transparent cup is almost colorless under the white light source, while the water in the heavy aquarium is light blue. Colorless, white and blue people usually answer this way: water is colorless, it is "transparent" and "clear"; The sea looks blue because it reflects the color of the sky. These views are wrong. Water is blue. Although the color is light, it is really blue. This can be found in nature. No matter the deep hole in the snow or the thick ice layer of the waterfall in winter, you can see that the water inside is blue. You can also dig a white pool big enough and deep enough and fill it with water. Looking vertically, you will be surprised to find that the water inside is blue. Since water is slightly blue, how to explain that seawater is sometimes striking blue? This needs to mention the reflection of seawater. In fact, the sea is blue, which is the result of reflection from the sky. On a cloudy day, you will find that the blue of the sea is not so striking. However, water not only reflects the light above the water surface, but also reflects the light below the water surface. The more impurities in water, the more mixed colors it reflects. In large water bodies such as oceans and lakes, there are usually highly dense phytoplankton and algae. In rivers and ponds, most of them contain high-density dust and other solid suspended substances. Light is reflected and scattered by these underwater substances at the bottom of the water, and the color we see is formed on the water surface. In this way, it can explain why the Mediterranean sometimes appears bright green on sunny days.
