A ray of light falls on a mirror normally. What are the values of angle of incedence and the angle of reflection.

Explanation

To solve the problem of determining the angles of incidence and reflection when a ray of light falls normally on a mirror, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Setup**:
- We have a mirror and a ray of light that strikes the mirror. The ray is said to fall "normally," which means it is perpendicular to the surface of the mirror.

2. **Define the Normal Line**:
...
