1st law = The incident ray, the refracted ray and the normal to the surface at the point of incidence all lie in one plane. 
2nd law = For any 
two given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. 
defination = change in the direction of wave propagation due to change in it transmission medium. 
causes – the speed of light is diffrent in diffrent medium , so, it changes its path . 
HOPE IT CLEARS
