Dual Nature Of Light Question 216

Question: If the momentum of a photon is p, then its frequency is [MP PET 1989]

Options:

A) $ \frac{ph}{c} $

B) $ \frac{pc}{h} $

C) $ \frac{mh}{c} $

D) $ \frac{mc}{h} $ Where m is the rest mass of the photon

Show Answer

Answer:

Correct Answer: B

Solution:

$ p=\frac{E}{c}=\frac{h\nu }{c},\Rightarrow \nu =\frac{pc}{h} $
