Momentum of photon with frequency f will be …..(where c is velocity of light)

A

`(hf)/(c^(2))`

B

hfc

C

`(f)/(c)`

D

`(hf)/(c )`

Text Solution

Verified by Experts

The correct Answer is:
D
Momentum of photon `p=(h)/(lambda)=(hf)/(c )[because (1)/(lambda)=(f)/(c )]`

    What is energy of photon having frequency v?

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

    No . Of photoelectron emited by light with frequency f is proportional to ….[Here frequency f gt threshold frequency f_(0) ]

    If E and p are the energy and momentum of a photon respectively then on decreasing in the wavelength of photon.

    A radiation of energy 'E' falls normally on a perfectly reflecting surface. The momentum transferred to the surface is (c = Velocity of light) :
