Two plane mirrors `M_(1)` and `M_(2)` each have length `1 m` and are separated by `1 cm`. A ray of light is incident on one end of mirror `M_(1)` at angle `45^(@)`. How many reflections the ray will have before going from the other end?

Two parallel plane mirrors M_(1) and M_(2) have a length of 2 m each and are 10 mm apart. A ray of light is incident on one end of mirror M_(2) at an angle of 30^(@) . The number of reflections light undergoes before reaching the other end is –
