Question
A reflected successively from from two plane mirrors inclined at at certain angle (< 90o) under goes a devotion of 300o. The number of image observable are:
Options
A.10
B.11
C.12
D.14
Solution
If the angle between mirrors is then the deviation from two plane mirrors will be = 2π - 2θ = 300 = 2π - 2θ ⇒ θ = 30o
Hence
= 12
Number of images = m - 1 = 12 - 1 = 11
Hence
= 12Number of images = m - 1 = 12 - 1 = 11
