7 electromagnetic waves By: Jonathan Larson

What is an electromagnetic wave? An electromagnetic wave is a wave that doesn’t need a medium to pass through in order to travel. There are 7 different types of electromagnetic waves.

Wave 1: Radio Waves Slowest of all waves Are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves occur by lightning, radio towers, and radio satellites. Examples: lightning and radiowaves

Wave 2: Micro Waves A subset of all radio waves. Micro waves can be as long as one meter to a short as one millimeter. Examples of micro waves: cell phone, microwave

Wave 3: Infrared Waves Is electromagnetic radiation with a wavelength longer than visible light or as far as the eye can see. Examples: night vision goggles, heat seeking goggles

Wave 4: visible light waves 3rd fastest wave of all seven Is basically the wave that comes off of light You can see it with the human eye. Examples: the sun, light tower

Wave 5: ultra violent waves Is light that has shorter wavelengths than visible light The wave is invisible to the human eye, though some insects such as bumblebees can see them. Examples: a sauna, a tanning bed

Wave 6: X-rays Everybody knows what an x-ray is. It is not visible to the human eye, but can see seen with an x ray machine. Everybody has seen an x-ray. Examples: an x-ray, x-ray machine

Wave 7: Gamma Rays Fastest of all waves. Nothing on the world can see a gamma ray. Is electromagnetic radiation of high frequency. Examples: x ray, radio wave
