One day, my father bought a painting from other places. My father said to me mysteriously, "Don't touch this painting, is it magic?" So, dad put the photo in the study. I asked my father, "What's so magical about a broken painting?" Dad said, "Haha, you don't know that!" " Because the color of this painting is different during the day and at night. "How can the same painting have different colors during the day and at night? Filled with curiosity, I decided to watch it again at night. In the evening, I sneaked into the study while my father was not looking. The result was beyond my expectation. This picture is still bright during the day, but how did it turn dark yellow at night? Did you use any special pigments? I shouted so loudly that my father heard me. Father rushed over and boasted, "Look, it's amazing! "! All right, get out! "
I look at this magical behind-the-scenes and think hard to find the reason here, but I still can't figure it out. So I went to check the information. An hour later, my efforts finally paid off. It turns out that this is all about the electric light. Because the color of an opaque thing is determined by the color of the light it reflects. It is bright during the day because blue light is reflected by its body. The reason why it is dark yellow at night is that the most light in the electric lamp is red light and orange light, and the blue light and purple light are pitiful. This is the reason why a painting has different colors day and night.
I was flattered to find the reason why the color of a painting is different during the day and at night. At the same time, I also know that an ordinary painting contains so much knowledge, so how much knowledge in nature is waiting for us to discover! So pay attention to observation and learn more about nature.
