Answer 2

Answer:

Concave mirrors are used as street light

reflectors.

The given statement is false.

Because Convex mirrors are used as street light reflectors which helps to spread the light in a wide area.

Explanation:

Spherical mirrors are of two types :

1. Concave mirror and
2. Convex mirror.

• A concave mirror is made by silvering the outer surface.

• A convex mirror is made by silvering the inner surface.

• The Light rays incident on it diverge after reflection.

• The image formed by a convex mirror is always diminished for all people positions of the object in front of it.
