OPTICS AND THE THEORY OF COLOR - 03. THE MAIN OPTICAL PHENOMENA

03. THE MAIN OPTICAL PHENOMENA

Optics is studying the optical phenomena - i.e. the laws of behavior of electromagnetic waves of visible range (and close to it other ranges) spreading in various mediums and bodies consisting of the chemical elements. Let's list all existing optical phenomena.
1) The emission of light;
2) The absorption of light;
3) The reflection of light;
4) The transmission of light;
5) The refraction of light;
6) The scattering of light.
Respectively, if we think that "light" - this is a flow of elementary particles of a certain quality, then we will consider all listed optical phenomena  not only in relation to visible photons, but also in relation to all other types of elementary particles.

It is very difficult to describe the optical phenomena separately of each other, because they are mutually interwoven and one accompanies the other. Processes of absorption and reflection can proceed in parallel. Reflection is always accompanied by the emission and absorption. Refraction and reflection underlie the scattering. And the reason of refraction and absorption is the same. And finally transmission always begins with emission or reflection, it is observed during this albeit insignificant scattering, and transmission ends eventually by absorption. Here such a relationship exists between the optical phenomena. And if to be precise - between the features of behavior elementary particles in physical media consisting of the chemical elements.
