Laws of refraction
1. The incident ray, the refracted ray and the normal at the point of incidence all lie on the same point
2. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant for a given pair of media
Sin i/ sin r= constant (k)
Refractive index
Refractive index (n) is the constant of proportionality in Snell’s law thus
Sin I / sin r =n
