Question

The momentum of a photon of an electromagnetic radiation is 3.3 x 10^-29 kg ms^-1. What is the frequency of the associated waves?

[h = 6.6 x 10^-34 Js; c = 3 x 10⁸ ms^-1]

(a) 1.5 x 10¹³ Hz 

(b) 7.5 x 10¹² Hz

(c) 6 x 10³ Hz 

(d) 3 x 10³ Hz

Answer 1

The correct option is (a) 1.5 x 10¹³ Hz.

Explanation:

Momentum of the photon = hv/c
