As light enters from air into glass slab, its wavelength

A

Wavelength increases

B

Wavelength decreases

C

Frequency increases

D

Frequences 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 `lambda` = decreases.
