Refraction through Parallel Faces
Refraction through Parallel Faces
A ray of light passes through the air (yellow) to a glass plate (blue) and then back into the air. By Snell's law, the angles of refraction at the first and second surfaces are equal and therefore the entry and exit rays are parallel.
