Question

Concave mirror finds use in huge reflecting telescopes. Give reason.

Answer 1

1. The major component of a reflecting telescope is the concave mirror.
2. The concave mirror is known as a converging mirror because it converges a ray of light travelling from infinity, to its focal point.
3. Since it is a converging mirror, the concave mirror helps in converging the light from a far-off object to a point. Hence, the concave mirror finds use in huge reflecting telescopes.
