Which lens is used in car side mirror?

Which mirror is used in street light?

Convex mirror is used in street light because it has the property of divergence . Therefore light rays coming from bulb diverges in convex mirror and cover a large distance . In case of a concave mirror ,it has property of convergence .

Are headlights concave mirrors?

Concave mirror are used in car headlamp. Concave mirror has converging power, it can concentrate the light ray at a particular point. And in night we want highly concentrated light beam for clear visibility. This is why concave mirror is used.

Where is concave mirror used?

Concave mirrors are used as searchlights, shaving mirrors, satellite dishes, and many more. These mirrors have the property to collimate and concentrate light rays. Concave mirrors in torches and headlights are used as reflectors.

How do you find the V in a mirror formula?

Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.
