The concave mirror can give an erect and enlarged image.
What is a 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.
- Concave mirrors provide real and virtual, erect and inverted, diminished, same-sized and magnified image depending upon the position of the object on the principal axis.
