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

**Step-by-Step Solution:** 1. **Understanding the Function of a Concave Mirror:** - A concave mirror is designed to focus light rays that are parallel to its principal axis to a single point known as the focus. This property allows torches to produce a concentrated beam of light. 2. **Effect of Rust on the Reflective Surface:** - When the concave reflecting surface of a torch becomes rusted, the smoothness and reflectivity of the surface are compromised. Rust creates an uneven surface that scatters light instead of reflecting it uniformly. ...
