Question

When light enters from a rarer medium to a denser medium:
A). Its frequency changes
18) Wavelength does not change
C) Its wavelength changes
D) Both wavelength and frequency change
hich of the given is not true of an image formed by a plane​

Answer 1

Explanation:

Note: When a ray of light enters from a rarer to denser medium light bends. But if the ray light moves from denser to rarer medium light moves away from the normal. Since the speed of light changes as it enters from a rarer to denser medium the frequency of light does not change but its wavelength changes
