An EM wave of intensity ‘I’ falls on a surface kept in vacuum. What is the radiation pressure if wave is totally reflected?

Explanation

To find the radiation pressure when an electromagnetic (EM) wave of intensity ‘I’ falls on a surface that is totally reflected, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Radiation Pressure**:
Radiation pressure is the pressure exerted by electromagnetic radiation on a surface. It depends on the intensity of the wave and how much of that wave is reflected, absorbed, or transmitted by the surface.

2. **Intensity of the EM Wave**:
