AI Generated Solution

To solve the problem where the incident ray and the reflected ray from a mirror are mutually perpendicular to each other, we will follow these steps: ### Step-by-Step Solution: 1. **Understand the Problem**: We know that the incident ray and the reflected ray are mutually perpendicular. This means that the angle between these two rays is 90 degrees. 2. **Define Angles**: - Let the angle of incidence be denoted as \( I \). ...
