n = c/v = sin i/sin r
Explanation:
- Refractive Index or Index of refraction is the measurement of the bending of light rays as light passes from medium to another.
- Refractive Index can be calculated by the following formula. It is the ratio of the speed of light in a vacuum to that of a medium.
- It is denoted by n.
n = Speed of light in vacuum/Speed of light in the medium = c/v
n = sin i/sin r where i is the angle of incidence and r is the angle of refraction.
