Electromagnetic waves (electromagnetic wave) is a type of wave that moves without relying on intermediaries. Based on the induction between the magnetic and electric, which change all the time.
The study also found that electromagnetic waves, the frequency range is unique, it has a different call sign. To sort from low frequency to high frequency shall be as follows: Radio waves, microwaves, infrared rays Light eyes X-rays and gamma rays All electromagnetic waves with continuous frequency include spectral called electromagnetic waves (electromagnetic spectrum)
