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.
