Optics

Optics is the branch of physics which involves the behaviour and properties of light,

including its interactions with matter and the					construction of instruments that use
or detect it. Optics	usually	describes		the	behaviour		of visible, ultraviolet,
and infrared light.	Because	light	is	an electromagnetic			wave,	other forms
of electromagnetic	radiation such as X-rays, microwaves,					and radio		waves exhibit
similar properties
Electromagnetic	radiation (EM		radiation or EMR)			is	a form of radiant

energy released by certain electromagnetic processes. Visible light is one type of electromagnetic radiation, other familiar forms are invisible electromagnetic radiations such as X-rays and radio waves.

Optical range - the whole range of vibration frequencies of electromagnetic waves, which can operate without being destroyed with devices of Physical Optics.

For frequencies lower than the frequencies of the optical band, it is difficult to construct optical systems according to the laws of physical optics, and electromagnetic field of higher frequencies, as a rule, passes through any substance without changing properties or destroys it.
