What are the types of electromagnetic radiation
Electromagnetic radiation, also known as electronic smog, is composed of electric energy and magnetic energy that are jointly transferred in space, and this energy is generated by the movement of electric charges. Electromagnetic energy is generated, for example, by mobile charges emitted by a radio-frequency antenna that is transmitting a signal. The electromagnetic "spectrum" includes all types of electromagnetic radiation, from very low frequency electromagnetic radiation to very high frequency electromagnetic radiation. There are also radio waves, microwaves, infrared, visible light, and ultraviolet light in between. The general definition of the radio frequency portion of the electromagnetic spectrum refers to radiation with frequencies from approximately 3 kHz to 300 GHz. Some electromagnetic radiation has a certain effect on the human body.
