A) 2
B) 3
C) 1
D) zero
Correct Answer: B
Solution :
The number of images formed depends upon the angle between the mirrors. If two mirrors make an angle\[\theta \]with each other, the number of images formed is \[n=\frac{360}{\theta }-1\] when mirrors are kept mutually perpendicular to each other, then\[\theta =90{}^\circ .\] \[n=\frac{360}{90}-1=3\]
