The linear momentum of a 3 MeV photon is

A

0.01 eV s/m

B

0.02 eV s/m

C

0.03 eV s/m

D

0.04 eV s/m

Text Solution

Verified by Experts

The correct Answer is:
A

Energy of a photon , E = 3 MeV = `3 xx 10^(6) eV`
Linear momentum of the photon , p `=E/c`
whre c is the speed of light in vacuum.
` p = (3 xx10^(6) eV)/(3 xx10^(8) m//s) =10^(-2) eVs//m = 0.01 eVs//m`

Light in certain cases may be considered as a stream of paerticles called photons. Each photon has a linear momentum h/lamda where h is the Planck's constant and lamda is the wavelength lamda is incident on a plane mirror at an angle of incidene theta . Calculate the change in the linear momentum of a photon as the beam is reflected by the mirror.

Find the momentum of a 12.0 MeV photon.

Let p and E denote the linear momentum and energy of a photon. If the wavelength is decreased,

Which of the following is correct regarding photons? (i) A photon always travels at a speed 3xx10^(8)m//sec in vacuum. (ii) The rest mass of photon is zero. (iii) Let E and p be the energy and linear momentum of a photon and v and lambda be the frequency and wavelength of the same light when it behaves as a wave. Then E=h v =(hc)/(lambda) p=(h v)/(c) =(h)/(lambda) =(E)/(c) (iv) A photon may collide with a meterial particle. The total energy and the total momentum remain conserved in such a collision. The photon may get absorbed and / or a new photon may be emitted. Thus, the number of photons may not be consverved.
