When a ray of light enters a glass slab form air,

A

Wavelength increases

B

Wavelength decreases

C

Frequency increases

D

Frequency decreases

Text Solution

Verified by Experts

The correct Answer is:
B
When a light ray enters from air to glass its frequency remains unchanged, velocity (in denser medium) decreases, so wavelength `lamda=(upsilon)/(n)` decreases.
