Question

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 ?​

Answer 1

Answer :-

️ (a) The mirror is of convex type️

(b) u = -5cm, m = 1/10

m = - (v/u)

⇒ 1/10 = - (v/(-5))

⇒ v = 5/10 = (1/2)m

Therefore,

1/v + 1/u = 1/f

⇒ 1/(1/2) + 1/(-5) = 1/f

⇒ 1/f = 2 – 1/5 = 9/5

∴ f = (5/9) m

So, radius of curvature = 2f = (10/9)m
