given : f = 20 cm

c = 40 cm

the mirror is concave as it is

a converging mirror

sol: u1 = 25 cm

this distance is between focus and

centre of curvature, so image will be

real, inverted and enlarged formed

beyond centre of curvature.

u2 = 15 cm

this distance is between focus and

pole, so image will be virtual

erect and enlarged formed behind

the mirror.
