(a) Calculate the momentum of a photon having a wavelength of 2.50 μm . (b) Find the velocity of an electron having the same momentum. (c) What is the kinetic energy of the electron, and how does it compare with that of the photon?

To determine

(a)

The momentum of a photon having wavelength 2.50 μm .

Explanation

Given info:

λ=2.50 μm

h=6.63×1034 Js1

Formula used:

For momentum in photon, the relation between photon and wavelength is

phλ

Calculation:

Value of wavelength is in micrometer convert it into m.

λ=2.50×106 m

Now momentum of photon is

p6

To determine

(b)

The velocity of an electron having the same momentum.

To determine

(c)

The kinetic energy of the electron, and compare it with that of the photon.
