A spherical mirror has focal length -10 cm. What type of mirror is it likely to be?

Answer :

The mirror is likely to be the concave mirror because the focal length of the concave mirror is negative because the focus is on the left-hand side of the mirror which is taken to be negative according to sign convention.
