Laws of Refraction


(i) The incident ray, the refracted ray and the normal to the transparent surface at the point of incidence all lie in the same plane.


(ii) The ratio of the sine of the angle of incidence in the first medium to the sine of the angle of refraction in the second medium is a constant for a given pair of medium and for a given wavelength of light.


n=sin i / sin r


Absolute refractive index of a medium is defined as the ratio of the speed of light in vacuum or air to the speed of light in the medium. It is denoted by n.


n=speed of light in air (c) / speed of light in medium (v)
