Reflection & Mirrors

To get three images of a single object, the angle between the two plane mirrors should be

Show answer and solution

Answer: (d)

  1. Number of images n=360∘θ−1n = \frac{360^\circ}{\theta} - 1 (when 360∘θ\frac{360^\circ}{\theta} is even).
  2. 3=360∘θ−1⇒θ=90∘3 = \frac{360^\circ}{\theta} - 1 \Rightarrow \theta = 90^\circ
  3. So the answer is (d) 90∘90^\circ.
