Electromagnetic radiation is a fluctuation
of energy. Description of electromagnetic radiation emission of
electromagnetic waves and spread through space or a medium to pass
their energy. The frequency of electromagnetic radiation in accordance
with generally divided into radio waves, microwaves, infrared light,
visible light, ultraviolet, X-rays and gamma rays and so on several
forms. Each band has the energy based on features that can be learned
at a very low temperature (near absolute zero time), only the atoms
within the material out of radio waves and microwave radiation; When
around zero degrees Celsius (freezing point of water) are atoms can be
infrared radiation light; in the surface temperature of about 1000
degrees Celsius, 5 to 6 substances (such as the sun's surface), can
there be of visible light radiation; in the surface temperature of
millions of degrees, there will be X-ray; to the surface temperature of
objects up to 10 billion degrees the surface, there will be gamma-ray
rendering. In addition to the surface temperature can explain the
different bands of electromagnetic radiation sources, the gas is
produced by light irradiation, "fluorescent effect", there will be a
small number of high-energy electromagnetic waves, such as ultraviolet
light, X-ray showed. As for the nuclear explosion, a supernova
explosion, then there will be a lot of ultraviolet light, X-ray and
gamma ray rendering.
