Fig(a) shows the ray diagram if the angle between mirrors is 45°. It can be seen from figure, the ray retraces itself at 2nd reflection.
Fig(b) shows the ray diagram if the angle between mirrors is 30°. It can be seen from figure, the ray incident normally before third reflection.
Hence it will retrace itself after third reflection
Fig(b) shows the ray diagram if the angle between mirrors is 30°. It can be seen from figure, there wont be any retracing
