Rule of refraction of light
1. Incident ray, refracted ray nd normal at the point of incidence, all lie in same plane.
2. The ratio of sin of incidence angle nd sine of refraction angle is constant for any two medium nd same colour of light. This is also called snell's law.
Sin i / sin r = constant
i is incidece angle nd r is refraction angle. This constant is called refractive index of second medium with respect to first medium.

Answer:
Explanation:
Refractive index is defined as the ratio of speed of light in a vacuum to speed of light in medium.
Rules of refraction:
1.Ratio of sine of angle of incidence to sine of angle of refraction is constant
2.Incident ray,refracted ray and normal lie on same plane.
