Pressure exeted by an electromagneti wave os intesnity `.I.` on a non - reflecting surface is given by
[Here c= speed of light]

A

`Ic`

B

`(I)/(c )`

C

`Ic^(2)`

D

`(I)/(c^(2))`

Text Solution

Verified by Experts

The correct Answer is:
B
For non - reflecting surface (i.e., the surface which `100%` absorbs the incident radiation) radiation pressure `P=(I)/(c )`.
