Question

Formula used when a light ray enters a medium of refractive index n₂ from a medium of refractive index n₁ at curved surface with radius of curvature R is

• A. \(\frac{n_2}{v} - \frac{n_1}{u} = \frac{n_2 - n_1}{R}\)
• B. \(v-u = \frac{n_2 - n_1}{R}\)
• C. \(\frac{v}{n_2} - \frac{u}{n_1} = \frac{n_2 - n_1}{R}\)
• D. \(\frac{n_2}{v}+\frac{n_1}{u} = \frac{n_2 - n_1}{R}\)

Answer 1

The Correct Option is A

The correct option is (A): \(\frac{n_2}{v} - \frac{n_1}{u} = \frac{n_2 - n_1}{R}\)
