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

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
