Electromagnetic Spectrum

Electromagnetic spectrum is the term used to describe the whole range of different types of electromagnetic radiation. In light waves, electric and magnetic fields vibrate therefore light is classified as electromagnetic radiation. This is an energy that travels and spreads out as it goes. Hotter, more energetic objects create higher radiation than cooler objects.

Some types of electromagnetic radiation include: radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. Visible light only takes up a small part of the spectrum. Everything on the spectrum may seem different, but they are still electromagnetic radiation.
