1. electromagnetic waves
The 7 types of waves

2. Ultraviolet
Is light that has short wave length visible light. Ultraviolet are in visible will the human eyes.
-They have soon find out that there are three ultraviolet, one were be NUV is an light closest to optical.
-the second would be the EUV ultraviolet closest to an x-ray.
-the three of them is FUV that is the farthest out of them least explored.

3. Radio waves
Radio waves have the longest waves length electromagnetic spectrum.
They stretch around the world to phones computer and other thing that you connected with in the world.
They also carry signals that are use in phone and other things
Because the radio wave are so long telescopes they work differently then telescopes.

4. Microwaves
Microwaves-have a vary wavelength that can be measured in centimeters.
The waves are the one who heat our food so can eat
Microwaves are good transmitting information to one place to another because of the energy penetrate.

5. Infrared
Infrared light-are in between visible and microwave of the electromagnetic spectrum.
Infrared has a range that wavelength this has visible has light that are red to violet.
Can detect heat from any thing with a heat paten that can help at some point in live, if it to finding someone or more people you can find easily.

6. X-rays At the wavelength of lights decrease they increase with energy.
X-rays have smaller wavelength therefore higher energy levels.
X-rays were first invented in 1895 by Wilhelm Conrad Roentgen.
X-rays are another way to see in side to see if any breaker bones they radiation for x-rays.

7. Gamma-rays
Gamma-rays: have the smallest waves and the most energy of all the waves.
Gamma-rays can kill living cells a fact which medicine uses to its advantage
Gamma-rays travel to us across vast distances of the universe only to be absorbed by the Earths atmosphere
Gamma-rays are the most energetic form of light and are produced by the hottest regions of the universe.

8. Visible Waves
Visible light waves are the only electromagnetic waves we can see.
We see these waves as the colors of the rainbow.
Each color has a different wavelength.
When a white light shine through a prism the white light breakers the color down.
