A diverging (convex) mirror has radius of curvature 5 cm.
(a) What is its focal length?

An object of size 1 cm is placed at distance (b) 5 cm and (c) 2.5 cm from the mirror. Calculate the distance and size of the image in each case, and state whether it's real or virtual. Draw ray diagrams to scale.
