Q1. A concave mirror is used in applications requiring a converging beam. Which of the following uses a concave mirror?
Answer: Searchlights and solar cookers
Explanation: A concave mirror reflects parallel rays to converge at a focal point, producing a powerful, directed beam; searchlights use a concave mirror with the light source at the focus to project a collimated beam, and solar cookers use one to concentrate sunlight.
