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

A

`(hupsilon)/c`

B

`(upsilon)/c`

C

`hupsilonc`

D

`(upsilon)/c^2`

Text Solution

Verified by Experts

The correct Answer is:
A
Energy of a photon, `E = h upsilon " "...(i)`
Also, `E = pc " "...(ii)`
where p is the momentum of a photon
From (i) and (ii), we get
`hupsilon = pc " or " p = (hupsilon)/c`
