An EM wave of intensity I falls on a surface kept in vacuum and exerts radiation pressure p on it. Which of the following are true?
a) radiation pressure is \mathrm{I} / \mathrm{c} if the wave is totally absorbed
b) radiation pressure is I / c if the wave is totally reflected
c) radiation pressure is 2 \mathrm{I} / \mathrm{c} if the wave is totally reflected
d) radiation pressure is in the range I / c<p<2 I / c for real surface

An EM wave of intensity I falls on a surface kept in vacuum and exerts radiation pressure p on it. Which of the following are true?
a) radiation pressure is \mathrm{I} / \mathrm{c} if the wave is totally absorbed
b) radiation pressure is I / c if the wave is totally reflected
c) radiation pressure is 2 \mathrm{I} / \mathrm{c} if the wave is totally reflected
d) radiation pressure is in the range I / c<p<2 I / c for real surface

The correct options are:

a) radiation pressure is \mathrm{l} / \mathrm{c} if the wave is totally absorbed

c) radiation pressure is 2 \mathrm{l} / \mathrm{c} if the wave is totally reflected

d) radiation pressure is in the range I / \mathrm{c}<\mathrm{p}<2 \mathrm{I} / \mathrm{c} for real surface
