A small angled prism is made of a material of refractive index \(\frac{3}{2}\). The ratio of the angles of minimum deviations when the prism is placed in air and in water of refractive index \(\frac{4}{3}\) is
- A \(4: 1\)
- B \(3: 4\)
- C \(2: 3\)
- D \(1: 3\)
Answer & Solution
Correct Answer
(A) \(4: 1\)
Step-by-step Solution
Detailed explanation
Deviation produced by a thin prism \(\delta=\mathrm{A}(\mu-1)\) In air, \(\left.8_1=\mathrm{A}_{\mathrm{a}} \mu_{\mathrm{g}}{ }^{-1}\right)=\mathrm{A}\left(\frac{3}{2}-1\right)=\frac{\mathrm{A}}{2}\) In water,…
