Question

An object is placed asymmetrically between two plane mirrors inclined at an angle of 72° . The number of images formed is (A) 5 (B) 4 (C) 2 (D) Infinite

Tardigrade Admin · Accepted Answer

n=(360 ° /72 ° )=5 Note that (360/θ ) is odd and the object lies asymmetrically

$n = \frac{36 0 ^{\circ}}{7 2 ^{\circ}} = 5$
Note that $\frac{360}{θ}$ is odd and the object lies asymmetrically
