The concave reflecting surface of a torch got rusted. What effect would this have on the beam of light from the torch?

Explanation

To understand the effect of rust on the concave reflecting surface of a torch, we can break down the problem into several steps:

### Step 1: Understanding the Function of a Concave Mirror
A concave mirror is designed to focus light rays that hit its surface. When light rays strike the concave surface, they reflect inward and converge at a focal point, creating a concentrated beam of light.

### Step 2: Effect of Rust on the Surface
When the concave reflecting surface of the torch gets rusted, the smoothness of the surface is compromised. Rust creates an uneven and rough texture on the mirror.
