When a convex lens is immersed in two different liquids of refractive indices 1.25 and 1.5. The ratio of the focal lengths of the lens is \(5: 16\). The refractive index of the material of the lens is
- A 1.55
- B 1.5
- C 1.65
- D 1.6
Answer & Solution
Correct Answer
(C) 1.65
Step-by-step Solution
Detailed explanation
In first liquid, \(\mu_1=1.25\) \(\therefore \frac{1}{\mathrm{f}_1}=\left(\frac{\mu_2}{1.25}-1\right)\left(\frac{1}{\mathrm{R}_1}-\frac{1}{\mathrm{R}_2}\right)\) In second liquid, \(\mu_1=1.5\)…
