Position of two plane mirrors and object O is shown in digram. Find the total number of image formed by the mirrors.

Answer:

Solution:

Angle between the mirrors: $θ = 3 0^{\circ} + 3 0^{\circ} = 6 0^{\circ}$

$m = \frac{36 0 ^{\circ}}{θ} = \frac{360}{60} = 6$ (even), so number of images = m - 1 = 5.

Answer: 5
