The ratio of the angle of deviation produced by a thin prism, when it is placed in air to the angle of deviation produced when it is immersed in water of refractive index \(\dfrac{4}{3}\) is:
- A \(4:1\)
- B \(9:8\)
- C \(1:4\)
- D \(8:9\)
Answer & Solution
Correct Answer
(A) \(4:1\)
Step-by-step Solution
Detailed explanation
The angle of deviation produced by a thin prism is given by \(\delta = (\mu_{rel} - 1)A\), where \(\mu_{rel}\) is the refractive index of the prism relative to the surrounding medium. Assuming the refractive index of the glass prism to be \(\mu_g = \dfrac{3}{2}\). When the prism…
