When a ray of ordinary light is incident on the surface of separation of two media at polarizing angle, show with the help of a labelled diagram that reflected ray and the refracted ray are mutually perpendicular to each other.

Explanation

To show that the reflected ray and the refracted ray are mutually perpendicular when a ray of ordinary light is incident on the surface of separation of two media at the polarizing angle, we can follow these steps:

### Step 1: Understand the Setup
Consider a boundary separating two media, medium 1 (with refractive index \( \mu_1 \)) and medium 2 (with refractive index \( \mu_2 \)). A ray of light is incident on this boundary at the polarizing angle \( \theta_p \).

### Step 2: Draw the Diagram
1. Draw a horizontal line representing the boundary between the two media.
2. Mark the incident ray approaching the boundary at an angle \( I \) (which is equal to \( \theta_p \)).
