Question

An object is placed at 100 mm in front of a concave mirror which produces an upright image (erect image). The radius of curvature of the mirror is: *​

Answer 1

Answer:

Since the image formed is upright, the object lies within the focus of the concave mirror.

So, f>100 mm

We know R=2f

So, R>200 mm

i.e. Radius of curvature is more than 200 mm.
