Question

The radiation pressure -

• A. depends on the nature of the surface on which it is falling.
• B. does not depend on the nature of the surface on which it is falling.
• C. does not depend on the source.
• D. None of these

Answer 1

The correct option is A depends on the nature of the surface on which it is falling.

The radiation pressure is given by,

$p=\frac{(1+e)I}{c}$

For the completely reflecting surface, $e=1$

For the completely absorbing surface, $e=0$

​​​​​​​Hence, option $\left(A\right)$ is the correct answer.
