Reflection is a physical process of interaction of waves or particles with the surface, changing the direction of the wave front at the boundary of two media with different properties, in which the wave front returns into the medium from which it came. The reflection may be specular (that is, such as is observed when using a mirror) or diffuse (in this case, the reflection is not saved the path of the rays from the object, but only the energy component of the luminous flux) depending on the nature of the surface. Simultaneously with the reflection of waves at media boundary, usually the refraction of waves (except total internal reflection).
Refraction (refraction) - changes the direction of propagation of waves of electromagnetic radiation that occurs at the interface of two transparent to these waves of media or in liquid medium with continuously varying properties. Refraction occurs when the phase velocity of electromagnetic waves in the contacting environment are different.

This includes the illusion associated with "wrong" colors, shadows, etc., turning ordinary things into unnatural.
