Q8.13Multiple correct
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 I/c if the wave is totally absorbed.
- (b)Radiation pressure is I/c if the wave is totally reflected.
- (c)Radiation pressure is 2I/c if the wave is totally reflected. (b) Radiation pressure is in the range I/c < p < 2I/c for real surfaces.
