Question

difference between concave and convex mirror?

Answer 1

Concave Mirror :

1. If the inner surface of the spherical mirror is reflecting surfaces, it is called concave mirror.

2. It is called converging mirror.

3. The focus lies infront of the mirror.
4. Can be projected on a screen.

Convex Mirror :

1. If the outer surface of a spherical mirror is the reflecting surface, it is called a convex mirror.

2. It is called diverging mirror.

3. The focus lies behind the mirror.

4. Cannot be projected on a screen.

Answer 2

Differences between convex and concave mirror:

Convex mirror:

1. The reflecting surface is curved outward.

2. After reflection from the mirror the light rays diverge.

3. The image formed due to convex mirror is always virtual and diminished.

4. It is used as rear view mirror.

Concave mirror:

1. The reflecting surface curved inward.

2. After reflection from the mirror the light rays converge.

3. The image formed due to concave mirror is generally real and either diminished or magnified. But when an object placed between vertex and focus it is virtual.

4. It is used in car headlights.
