Question

When the ray of light passes from denser medium to rare medium then speed and wavelength of light...​

Answer 1

Explanation:

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.

Answer 2

Answer:

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.
