∵ Angle of incidence = Angle of reflection
And ∠i (angle of incidence) = 0
So ∠r (angle of reflection) = 0
So, the light returns back to its path.

(i) How many mirrors should he use to see the objects? (ii) Indicate the positions of the mirrors in the figure. (iii) What must be the angle with respect to the incident light at which he should place the mirrors? (iv) Indicate the direction of rays in the figure. (v) If any of the mirrors is removed, will he be able to see the objects?
