Overview
Essential details:3096-1000 Electromagnetic radiometer APPLIED MATERIALS
Electromagnetic radiation consists of electric and magnetic fields that oscillate in the same direction
and are perpendicular to each other and transfer momentum and energy in the form of waves in space,
and its propagation direction is perpendicular to the plane composed of electric and magnetic fields.
The interaction between electric and magnetic fields produces electromagnetic waves,
which are emitted or propagated into the air to form electromagnetic radiation.
Electromagnetic radiation is composed of electrical and magnetic energy transferred by space together,
and this energy is generated by the movement of electric charges. For example,
the moving charge emitted by a radio-frequency antenna that is transmitting a signal generates electromagnetic energy.

The electromagnetic “spectrum” includes a wide variety of electromagnetic radiation,
from extremely low frequency electromagnetic radiation to high frequency electromagnetic radiation.
Between the two are radio waves, microwaves, infrared, visible light and ultraviolet light.
The general definition of the radio frequency portion of the electromagnetic spectrum refers to radiation with frequencies ranging from about 3 KHZ to 300 GHZ.
Some electromagnetic radiation has a certain effect on human body.
