Key Points
- 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 concave mirror.
- In this mirror 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, erect and virtual image is obtained.
- However, if the distance between the object and the mirror increases, the size of the image is formed inverted at the same point of the object where it is located and hence we obtain a real and inverted image.
- Thus, when an object is kept at the centre of curvature of a concave mirror, the image will be formed at the centre of curvature itself.
