When a ray of light enters water from air it is noticed that the ray does not continue in a straight line. Instead it gets bent with the relation between the angle of incidence of the beam and the angle of refraction of the beam being the same. The relation of the two angles in terms of the refractive indexes of the mediums is given by the Snell's Law as:
sin Ai / sin Ar = Nw / Na, where Ai is the angle of incidence, Ar is the angle of refraction, Nw is the refractive index of water and Na is the refractive index of air.
The refractive index of water is approximately 1.333 and that of air is approximately 1. Using the formula given the angle of incidence is more than the angle of refraction.
