Question
A ray reflected successively from two plane mirrors inclined at a certain angle undergoes a deviation of $270^o$ after total two reflections. The number of images observable are
✓
Answer
c
$\delta=360-2 \theta \Rightarrow \theta=45$
$\delta=360-2 \theta \Rightarrow \theta=45$
Angle between the mirror $\theta=45$
no. of Imager $=\frac{360}{45}-1=7$
