Absorption
Absorption
Absorption of electromagnetic radiation is how matter takes up a photon's energy (typically electrons within atoms). This transforms EM energy into internal energy of the absorber (thermal energy).

Reflected light can be divided into two subtypes, specular reflection and diffuse reflection.
Reflected light can be divided into two subtypes, specular reflection and diffuse reflection.
Specular reflection, also known as regular reflection, is the mirror-like reflection of waves, such as light, from a surface. The result is that an image reflected by the surface is reproduced in mirror-like (specular) fashion.

Specular reflection reflects all light which arrives from a given direction at the same angle, whereas diffuse reflection reflects that light in a broad range of directions.

Reflections that undergo scattered reflections are called diffuse reflections.
