A shop security mirror 5.0 m from certain items displayed in the shop produces one-tenth magnification.
(a) What is the type of mirror ?
(b) What is the radius of curvature of the mirror ?
(a) the type of mirror is Convex mirror
(b) Magnification = 1/10 = v/u
u = 10v
Object distance = 5m
Using mirror formula,
Focal length = 4.5m
Radius of curvature = 2f=9m0
