● The incident ray , the refracted ray and the normal to the interface of two transparent media at the point of incidence , all lie on the same plane .
● The ratio of sine of angle of incidence to the sine of angle of refraction for light of given colour is constant for a given pair of media . ( Snell's law )
sin i
____ = n ( constant ) .
