When light is refracted which of the following does not change?

A

Amplitude

B

Velocity

C

Frequency

D

Wavelength

Text Solution

Verified by Experts

The correct Answer is:
C
When light changes the medium, then frequency is the property which does not change but velocity and wavelength are modified according to medium. Some amount of energy is reflected and some is transmitted and hence amplitude of refracted light will also change.
