Question

Does the frequency of a ray of light change upon refraction.

Answer 1

1. No, During the refraction of light from one medium to another, its frequency will not change. This is because it is the characteristic of light, which does not depend on the medium.
2. When a body undergoes refraction, there will be a change in velocity. It is a must condition.
3. When a ray of light travels from a lighter medium to a denser medium, velocity decreases and if a body moves from a denser to a lighter medium, velocity increases.
4. Frequency never changes due to refraction. It will be constant throughout.
