Question

Match the following:

List I: Angles between two parallel mirrors

List II: Number of images formed by the two mirrors

Answer 1

When $\theta ={30}^0$, $n=\frac{360}{30}-1=11$

When $\theta ={45}^0$,$n=\frac{360}{45}-1=7$

When $\theta ={60}^0$, $n=\frac{360}{60}-1=5$

When $\theta ={72}^0$, $n=\frac{360}{72}-1=4$
