13.2. Reflection of Light http://www.ck12.org
- law of reflection:The law of reflection says that the angle at which the wave is incident on the surface equals
the angle at which it is reflected. - regular reflection:If a parallel beams of light falls on a smooth surface, the reflected beams are also parallel.
- diffuse reflection:When the reflecting surface is rough, parallel incident beams of light would be reflected in
non-parallel, random directions.
