MCQ
Radiation pressure on any surface:
  • A
    Is dependent on wavelength of the light used
  • Is dependent on nature of surface and intensity of light used
  • C
    Is dependent on frequency and nature of surface
  • D
    Depends on the nature of source from which light is coming and on nature of surface on which it is falling.

Answer

Correct option: B.
Is dependent on nature of surface and intensity of light used

Radiation pressure is given by $\text{P}_\text{R}=\frac{(1+\alpha)\text{I}}{\text{C}}$
where α is the coefficient of reflection of the surface.
For completely reflecting surface $\alpha=1$
For completely absorbing surface $\alpha=0$
So, radiation pressure depends on the nature of surface on which the light is falling but independent of wavelength of light falling.
