					 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
