A radiation of energy `E` falls normally on a perfctly refelecting surface . The momentum transferred to the surface is
A
`Ec`
B
`2E//c`
C
`E//c`
D
`E//c^(2)`
Text Solution
Verified by Experts
The correct Answer is:
B
Momentum of photon `= (E)/(c )` change in momentum`= (2E)/(c )` = momeutum transferred to the surface (the photon will reflect with same magnitude of momentum in opposite direction)
