Answer 2

Answer:

Concave Mirror

If a hollow sphere is cut into parts and the outer surface of the cut part is painted, then it becomes a mirror with its inner surface as the reflecting surface. This type of mirror is known as a concave mirror.

Characteristics of Concave Mirrors

• Light converges at a point when it strikes and reflects back from the reflecting surface of the concave mirror. Hence, it is also known as a converging mirror.

• When the concave mirror is placed very close to the object, a magnified and virtual image is obtained.

• However, if we increase the distance between the object and the mirror then the size of the image reduces and a real image is formed.

• The image formed by the concave mirror can be small or large or can be real or virtual.
