What is the ELECTROMAGNETIC SPECTRUM

The Electromagnetic Spectrum is made up of EM waves that are composed of oscillating magnetic and electric fields. This is why they are called ‘electromagnetic’ waves.

The electromagnetic spectrum contains radio waves, microwaves, light,x-rays, gamma rays, and more. Transcript http://www.moomoomathblog.com/2020/06/what-is-electromagnetic-spectrum.html
