Question
To get three images of a single object, one should have two plane mirrors at an angle of
Options
A.60o
B.90o
C.120o
D.30o
Solution
The number of images formed of two plane mirrors are placed at an angle θ is n = 
-1
Here n = 3
∴ 3 = -1
⇒ θ =
= 90o
-1 Here n = 3
∴ 3 =
-1 ⇒ θ =
= 90oCreate a free account to view solution
