Detailed Solution

Refraction:
When a beam of light travels from one medium to another, it deviates from its actual path.
The angle of incidence:
The angle between a ray that is incident on a surface and the line perpendicular to that surface at the normal to the point of incidence.
The angle of refraction:
At the point of incidence, the angle between the refracted ray and the normal
The angle of emergence:
When a beam of light travels from one medium to another, the angle of the light coming out of a medium.
