Question

Radius of curvature of a mirror is 20 cm. what type of mirror is it

Answer 1

Since the the radius of curvature is positive, so the focal length will be positive and by sign convention, we know that, the focal length of a convex mirror is always positive.

Thus, the answer to your query is "Convex Mirror".

Hope this helps....

Answer 2

Answer:

The mirror is a convex mirror.

Explanation:

It will be a convex mirror because as we are given that radius of curvature of mirror is positive, therefore the focal length will be positive as well because R=2f or the answer could be known by sign convention.
