  • A concave mirror is used in Headlights, Shaving mirrors and in Torches

Concave Mirror

Explanation

As a Shaving mirror

Concave mirrors at less distance produced magnified, upright images, therefore, are used as a shaving mirror

In Headlights

In case of headlights and searchlights, the light should not scatter and instead should be a parallel beam so that it can cover a longer distance.

For this purpose, concave mirrors are used because a parallel beam of light is produced when the light source is placed at the focus of a concave mirror.

In Torches

Concave mirrors reflect the light inward to one focal point and they are used to focus light.
