JKBOSE Physics: Solved Previous Year’s Question Paper for NCERT/CBSE Class 12th Physics Paper Code (HSEIIRKON17–A)

Question: Why does the sun look blue? Explain
Answer: Sunlight appears blue because of Rayleigh scattering, which is a type of scattering that occurs when light passes through a medium. When sunlight enters the Earth’s atmosphere, it interacts with molecules of nitrogen and oxygen, which scatter blue light more effectively than other colours. This causes the sky to appear blue, and the sun to appear even more blue because it is a much brighter source of light.
