What is the relation between refractive indices of media, object dist

1.	What is the relation between refractive indices of media, object distance, image distance and radius of curvature?
Answer» The relation between refractive indices of media, object distance, image distance and radius of curvature is given by \(\frac{n_2}{v}-\frac{n_1}{u}=\frac{(n_2-n_1)}{R}\) In the case of plane surfaces, R & f are infinity. Power is equal to zero. ∴ \(\frac{n_2}{v}=\frac{n_1}{u}\) Each curved surface of a lens is part of a sphere.

Answer»

The relation between refractive indices of media, object distance, image distance and radius of curvature is given by

\(\frac{n_2}{v}-\frac{n_1}{u}=\frac{(n_2-n_1)}{R}\)

In the case of plane surfaces, R & f are infinity. Power is equal to zero.

∴ \(\frac{n_2}{v}=\frac{n_1}{u}\)

Each curved surface of a lens is part of a sphere.
