The minimum deviation produced by a hollow prism filled with a certain liquid is found to be \(30^{\circ}\). The light ray is also found to be refracted at an angle of \(30^{\circ}\). Then the refractive index of the liquid is
- A \(\sqrt{2}\)
- B \(\sqrt{3}\)
- C \(\sqrt{\frac{3}{2}}\)
- D \(\frac{3}{2}\)
Answer & Solution
Correct Answer
(A) \(\sqrt{2}\)
Step-by-step Solution
Detailed explanation
For prism, \(\mathrm{s}_{\mathrm{m}}=30^{\circ}, \mathrm{r}=30^{\circ}\) \(\therefore \quad A=2 r=2 \times 30^{\circ}=60^{\circ}\) \(\therefore\) Refractive index, \(\mu=\frac{\sin \left(\frac{A+S_m}{2}\right)}{\sin \frac{A}{2}}\)…
