If the total electromagnetic energy falling on a surface is `U` then the total momentum delivered (for complate absorption) is

A

`(U)/(c)`

B

cU

C

`(U)/(c^(2))`

D

`c^(2)U`

Text Solution

Verified by Experts

The correct Answer is:
A
Momentum `P= (U)/(c)`(for complete absorption)
`P= (2U)/(c)`(for complte reflection).
