## The Electromagnetic SpectrumBy: Faelynn Dunham

Relationship between Frequency and Wavelength:

The higher the frequency, the shorter the wavelength. You can also multiply the frequency of a wave by its wavelength to find the speed of the wave.

The wave length range is approximately 10 cm - 10 m and the frequency range is about 3x10^7 - 3x10^9. Radio waves can be made naturally by lighting and other astronomical occurrences or man made by radio towers. They are used in navigation systems, communication satellites, radar, and computer networking.

Microwaves

The wave length range is approximately 1 mm - 10 cm and the frequency range is about 3x10^9 - 3x10^11. They are like a high frequency radio wave mad by various types of transmitters. Microwaves can be used to cook food, such as in the "microwave" in a kitchen. They are also in mobile phones, WiFi, and radars. By looking at high levels of microwaves for a long time, you can get cataracts that cloud your eyes and prevent you from seeing clearly if you can see at all.

Infrared light

The wave length range is approximately 3 mm - 30 mm and the frequency range is about 10^13 - 10^14. We used Inferred waves to heat up food and cook with a thermal inferred light. TV remotes also us inferred waves, but since they are short, we can't feel them.

Visible light

The wave length range is approximately 400 nm - 700nm and the frequency range is about 4x10^14 -7x10^14. The Sun naturally produces viable light and tiny cone receivers in our eyes process the waves to see the reflection of the sunlight off of things around us.

Ultraviolet light

The wave length range is approximately 200 nm - 400nm and the frequency range is about 7x10^14 -1.5x10^15. Some food and drug companies use UV lamps to sterilize their products.

X-rays

The wave length range is approximately 100keV and the frequency range is about 3x10^16 - 3x10^19. X-rays are produced by firing electrons at a metal target and are typically used for medical imaging. They can also be used treating cancer and in exploring outerspace.

Gamma rays

The wave length range is approximately 100 keV and the frequency range is about 3x10^19. Gamma waves are produced by nuclear and some other high energy processes. They are also used in medicine to treat internal organs, to kill cancer cells, to sterilize medical equipment and in radioactive tracers.
