A photon of light enters a block of glass after travelling through vacuum. The energy of the photon on entering the glass block

A

increases because its associated wavelength decreases

B

Decreases because the speed of the radiation decreases

C

Stays the same because the speed of the radiation and the associated wavelength do not change

D

Stays the same because the frequency of the radiation does not change

Text Solution

Verified by Experts

The correct Answer is:
D
Frequency of light does not change with medium.
