A radiation of energy 'E' falls normally on a perfectly reflecting surface. The momentum transferred to the surface is ( c = velocity of light)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
The radiation energy is given by 
Initial momentum of the radiation is 
.
The reflected momentum is 
So, the change in momentum of light is
Thus, the momentum transferred to the surface is 
.
