Question

When ray of light enters in glass slab from diamond

4 points

A Velocity decreases

B Wavelength increases

C Wavelength decreases

D Frequency increases​

Answer 1

Explanation:

On entering a glass slab the velocity decreases. v=νλ

Frequency is inherent property of a wave and does not change. So the wavelength decreses which results in reduction in velocity on entering a glass slab from air.

Answer) C. its wavelength decreases.
