Reflection is an inherent effect on all interfaces between materials of
different optical density (i.e. ior, speed of light in the material)
The amount of reflection depending on the incident angle and the materials
can be calculated with the fresnel equations. This works for both a
transit from less dense to more dense medium as well as the other way
round. More information can be found in the links from:
