To get three images of a single object, the angle between the two plane mirrors should be
- A \(50^{\circ}\)
- B \(60^{\circ}\)
- C \(72^{\circ}\)
- D \(90^{\circ}\)
Answer & Solution
Correct Answer
(D) \(90^{\circ}\)
Step-by-step Solution
Detailed explanation
As the object is placed symmetrically, \(\mathrm{n}=\left(\frac{360^{\circ}}{\theta}-1\right) \Rightarrow 3=\left(\frac{360^{\circ}}{\theta}-1\right) \Rightarrow \theta=90^{\circ}\)
