The refracted ray, incident ray and normal all lie in the same plane.
The ratio of sine of angle of incidence and angle of refraction is constant.
Absolute refractive index is defined as the ratio of the velocity of light in vaccuum to the velocity of light in medium.
Expression to relate speed of light in vacuum=
n=c/v
