Question

Properties of convex and concave mirror

Answer 1

Answer:

Explanation:

Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object.

2) Convex mirror always produces virtual and erect images. 3) The image formed by the convex mirror will be always diminished. When the outer surface is reflecting surface it is called convex mirror. they are always upright and not enlarged even when we move the object close to the mirror.
