The velocity of light in vacuum can be c...

The velocity of light in vacuum can be changed by changing ......

A

amplitude

B

frequency

C

wavelength

D

medium

Text Solution

Verified by Experts

The correct Answer is:
D
Refractive index,
`n=c/v` (Where c constant)
`therefore n prop 1/v`
So, if medium is changed, n also changes and accordingly velocity also changes.
