Question

Name the mirror that can give an erect and enlarged image of an object.

Answer 1

Concave mirror:

1. If we cut a hollow sphere 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.
2. The mirror obtained by this is known as a concave mirror.
3. This type of mirror has a reflective surface that is curved inward and away from the light source.
4. These types of mirrors reflect light inward to one focal point namely focii of the mirror.
5. The image formed by a concave mirror gives different image types depending on the distance between the object and the mirror.
6. Light converges at a point when it strikes and reflects back from the reflecting surface of the concave mirror. Hence, it is also called a converging mirror.
7. When the concave mirror is placed close to the object, we get a magnified and virtual image.
8. Concave mirrors provide real and virtual, erect and inverted, diminished, same-sized and magnified images depending upon the position of the object on the principal axis.

Thus, a concave mirror is one that can give an erect and enlarged image of an object.
