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 incident is equal to angle of reflection .
angle i = angle r
2. the incident wave reflected wave and the normal wave all lie in the same plane at the point of incident.
