Laws of refraction state that: The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane. The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant.

1) Angle of incidence is always equal to the angle of refraction.
2)The incident ray,the refracted ray and the normal to the point of incidence all lie on one plane.
