A prism is made of a glass having refractive index \(\sqrt{2}\). If the angle of minimum deviation is equal to angle of the prism, then the angle of prism is
- A \(45^{\circ}\)
- B \(90^{\circ}\)
- C \(60^{\circ}\)
- D \(30^{\circ}\)
Answer & Solution
Correct Answer
(B) \(90^{\circ}\)
Step-by-step Solution
Detailed explanation
Let \(\delta_m\) be the angle of minimum deviation. As we know that, \(\mu=\frac{\sin \left(\frac{A+\delta_m}{2}\right)}{\sin \frac{A}{2}}\) Given, \(\quad \mu=\sqrt{2}\) and \(A=\delta_m\)…
