1. 7 electromagnetic waves
By: Jonathan Larson

2. 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.

3. 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

4. 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

5. 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

6. 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

7. 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

8. 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

9. 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
