An EM wave of intensity I falls on a surface kept in vacuum and exerts radiation pressure p on it.

Which of the following is wrong?

A) Radiation pressure is \[\frac{I}{c}\] if the wave is totally absorbed

B) Radiation pressure is \[\frac{I}{c}\] if the wave is totally reflected

C) Radiation pressure is \[\frac{2I}{c}\] if the wave is totally reflected            

D) Radiation pressure is in the range \[\frac{I}{c}<p<\frac{2I}{c}\] for real surfaces
