Photon of frequency `v` has a momentum associated with it . If `c` is the velocity of light , the momentum is

A

`hc//c`

B

`v//c`

C

`h v c `

D

`h v//c^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Energy of a photom of frequency v is given by `E = hv ` also `E = mc^(2) , mc^(2)= hc`
`rArr mc = (h v)/( c) rArr p = (h v)/( c)`
