(1) the radio waves - wavelength from thousands of meters to 0.3 meters, general in this wave, television and radio band;

(2) microwave wavelength - from 0.3 m to 10 ^ - 3 meters, the wave multi-purpose in radar or other communication system;

(3) infrared - wavelength from 10 ^ - 3 meters to 7.8 * 10 ^ 7 meters;

(4) the visible light - this is what people can is a narrow band of light. From 780-380 nm wavelength. Was the motion of the electrons of the atoms or molecules in change of electromagnetic waves. Since it is the feelings we can directly detect the electromagnetic waves that part of the few;

(5) wavelength uv - from 3 x 10 x 10 ^ ^ - 7 m to 6-10 meters. The causes of these waves and light waves, often at the time of discharge. Because of its energy and general chemical reactions involved in the size, so the effect of ultraviolet light chemical strongest;

(6) X ray (X-ray) - this part of the electromagnetic spectrum,

The laser

Wavelength from 2 x 10 x 10 ^ ^ - 9 meters to 6 to 12 meters. X ray (X-ray) is the atomic inner electron electric by a state or state to jump to another given out by the electrons in the atom nuclear power field slows down;

(7) gamma rays - the wavelength from 10 10-10 ^ - ^ - 14 meters of the electromagnetic waves. The invisible electromagnetic wave emitted from the nucleus, radioactive substances and has a tendency to this radiation is accompanied by nuclear reactions. Gamma rays wear through strong, of biological damage is very large. It seems that the laser energy is not very big, but it is a big energy density (because its scope is very small, usually only one point), can short time to gather up a lot of quantity, used to make weapons, can understand.
