Answer 1

Answer:

Explanation:

A concave mirror finds its use in a headlight and telescope. It spreads the light of the bulb in a headlight and acts as a reflector in a telescope. It is readily available on online shopping sites. Its focal length can be of any length, but typically we get a concave mirror of 15 to 20 cm focal length.
