The directions of physics postgraduate entrance examination are: theoretical physics, material physics, condensed matter physics, optics and photonics, astrophysics and biophysics.
1, theoretical physics: mainly studies the basic principles and laws of physics, such as quantum mechanics, relativity, field theory, etc.
2. Material physics: mainly study the structure, properties, preparation and application of materials, including semiconductors, superconductors and photoelectric materials.
3. condensed matter physics: it mainly studies the properties and phenomena of electrons, magnetism and sound waves in solid substances, such as crystallography, magnetism and superconductivity.
4. Optics and photonics: I mainly study optical principles, optical devices and optical applications, such as optical fiber communication and laser technology.
5. Astrophysics: It mainly studies the formation, evolution and properties of various celestial bodies in the universe, such as cosmology and radio astronomy.
6. Biophysics: mainly studies the relationship between life phenomena and physical laws, such as the structure, function and dynamics of biological macromolecules.
Precautions for postgraduate entrance examination:
1. Candidates should bring their ID cards, admission tickets, etc. Do not bring any books, periodicals, newspapers, manuscript papers, pictures, materials, tools with communication functions (such as mobile phones, Bluetooth headsets, photographic equipment and scanning equipment) or electronic products with storage, programming and inquiry functions, as well as correction fluid, correction tape, transparent tape and other items into the examination room.
Candidates can only start answering questions after the test signal is issued. And after the 15 exam, late candidates are not allowed to enter the examination room to take the local exam, and the time for handing in papers should not be earlier than 30 minutes before the end of the local exam. Candidates are not allowed to enter or stay in the examination room again after handing in their papers.
Candidates must keep quiet in the examination room. Don't smoke, make noise, whisper, look around, gesture or signal, don't entrain, peek, copy or intentionally let others copy, don't copy test questions, answers or exchange test papers, answer sheets, answer sheets and draft papers, and don't intentionally damage or take them out of the examination room.
