A spherical mirror 'A' always forms an erect image of an object and another spherical mirror 'B' forms erect as well as inverted image of an object. State with reasons the type of spherical mirrors 'A' and 'B' and draw ray diagrams showing formation of images to justify your answer.(All India - 2013)

Answer:
A is convex mirror B os concave mirror
A spherical mirror 'A' always forms an erect image of an object and another spherical mirror 'B' forms erect as well as inverted image of an object.
The reasons and the type of spherical mirrors 'A' and 'B' are are stated below:
1. 'A' is a convex mirror.
2. As convex mirrors converge a beam of light on the other side of the mirror, they always form an upright and diminished image.
3. 'B'is a concave mirror.
4. Concave mirrors are diverging in nature and produce-
i. a diminished and inverted image when the object is placed beyond the focus of the mirror.
ii. an enlarged and upright image when the object is placed between the focus and centre of mirror.
Both the cases are illustrated in the ray diagrams below.
