Physics · Electromagnetic Waves
An electromagnetic wave of intensity I falls on a surface kept in vacuum and exerts radiation pressure p on it (c is the speed of light). Consider the following statements: (I) Radiation pressure is Ic if the wave is completely absorbed. (II) Radiation pressure is Ic if the wave is completely reflected. (III) Radiation pressure is 2Ic if the wave is completely reflected. (IV) Radiation pressure is in the range Ic < p < 2Ic for real (partially reflecting) surfaces. Which of the above statements are correct?
