Question

Photon of frequency v has a momentum associated with it. If c is the velocity of light, the momentum is
  1. v/c
  2. hvc
  3. hv/c2
  4. hv/c

A
v/c
B
hv/c
C
hvc
D
hv/c2
Solution
Verified by Toppr

We know that energy of photon is E=hν....(1)
Momentum of photo , p=mc=mc2/c=E/c where E=mc2
using (1), p=hν/c
