Questions  

The momentum of a photon of an electro magnetic radiation radiation is 3.3×1029kgm/s. What is the frequency of associated waves? 

(h=6.6×1034JS and c=3×108m/s)

a
3×103 Hz
b
6×103 Hz
c
7.5×1012 Hz
d
1.5×1013 Hz

detailed solution

Correct option is D

p=hνc⇒ν=pch=3.3×10−29×3×1086.6×10−34Hz=1.5×1013Hz
