A radiation of energy \(E\) falls normally on a perfectly reflecting surface. The momentum transferred to the surface is ( \(c\) is velocity of light)
- A \(Ec\)
- B \(E / C\)
- C \(2 E / C\)
- D \(E / c^2\)
Answer & Solution
Correct Answer
(C) \(2 E / C\)
Step-by-step Solution
Detailed explanation
Energy of the radiation is \(E\). \(\therefore\) Momentum of incident radiation, \(p=\frac{E}{c}\) \(\therefore\) Momentum of reflected radiation, \(p^{\prime}=-\frac{E}{c}\) (-ve sign arise to indicate the direction, i.e. direction of incident and reflected radiations are…
