Photon Of Frequency Has A Momentum Associated With It Physics Question

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

Options

(a) hν/c
(b) ν/c
(c) hνc
(d) hνc²

Correct Answer:

hν/c

Explanation:

Energy of a photon E = hʋ —–(i)
Also, E = pc —(ii)
Where p is the momentum of a photon
From (i) and (ii), we get
hʋ = pc ⇒ p = hʋ / c.
