A man stands symmetrically between two large plane mimors fixed to two adjacent walls of a rectangular room. The number of images formed are
- A 4
- B 3
- C 2
- D 6
Answer & Solution
Correct Answer
(B) 3
Step-by-step Solution
Detailed explanation
Number of images when an object is placed symmetrically between plane mirrors inclined at an angle \(\theta\), is given as \[ n=\frac{360}{\theta}-1 \] Here, \[ \begin{array}{ll} \text { Here, } & \theta=90^{\circ} \\ \therefore & n=\frac{360}{90}-1=4-1=3 \end{array} \]
