The way a ray of light refracts when it is incident on the surface separating two media depends not only on the refractive indices of the media but also on the angle of incidence.
In the given figure there are two mediums : Air and Water. Let their refractive indices be and respectively. The two media can be any pair such as air and water, or air and glass. Suppose a ray of light called as incident ray traveling in medium air, is incident on the surface of water body . Draw a normal to the surface at the point of incidence of incident ray.
The formed between the incident ray and the normal is called the angle of incidence.
The between the refracted ray and the normal is called the angle of refraction.
The ray of light inside the medium is called as refracted ray.
Two laws of refraction governs the refraction that takes place at a surface of separation.
