Refraction at Spherical Surface

Refraction at Spherical Surface

### Formula

$$\frac{\mu_2}{v}-\frac{\mu_1}{u}=\frac{\mu_2-\mu_1}{R}$$

### Terminologies

- μ1, μ2 → Refractive indices of mediums.

- u → Object distance.

- v → Image distance.

- R → Radius of curvature.

### Usage

- Used in curved surface refraction problems.
