The momentum of a photon of an electromagnetic radiation is 3.3 × 10–29 kg ms–1. What is the frequency of the associated waves ?
[h = 6.6 × 10–34 Js; c = 3 × 108 ms–1)
-
- 1.5 × 1013 Hz
- 7.5 × 1012 Hz
- 6.0 × 103 Hz
- 3.0 × 103 Hz
Correct Option: A
As λ = | and λ = | ; | ||
P | v |
so v = | = | |||
λ | h |
3 × 108 × = | 6.6 × 10-34 |
= 1.5 × 1013 Hz
