= The Electro-Magnetic Spectrum = = = = = media type="custom" key="3781913"
 * The Electro-Magnetic Spectrum is the list of all the possible electromagnetic frequencies

===If you didn't notice...as the frequency gets higher, the wavelength gets shorter or closer together. Also, the most energy is needed when the frequency gets bigger. So gamma rays produce the most energy...Radio Waves produced the least energy.===

Longest wavelengths λ Radio Waves are produced when charged particles move back and forth in instruments such as antennas They can be disturbed by obstacles and weather
 * __Radio Waves__ **

** __Microwaves__ ** Highest frequency of RADIO WAVES  Wavelengths  λ are only a few centimeters long   The water from the food absorbs energy, which produces heat. This is how a microwave works.

__** Infrared Rays **__  These frequencies are slightly lower than Visible Light Rays  Cannot be seen, but can be felt as heat (light bulbs, stoves, sun)  All objects give off some quantity of infrared; the quantity just depends on the temperature of the object.  Hotter objects give off more infrared rays

 Red , orange , yellow , green , blue , indigo , and violet are the possible visible colors  Visible Light is the smallest portion of the spectrum  Visible Light is very important!! We couldn’t survive without it.  Visible Light is needed for Photosynthesis which produces oxygen which keeps us alive! The speed of light is 299,792,458 meters per second...REALLY FAST!

** __Ultra-Violet Rays (UV Rays)__ **  Frequencies are just higher than Visible Light  UV Energy is great enough to kill living cells  UV lamps are used in hospitals and green houses to kill bacteria and to preserve foods and nutrients in plants.

__X-Rays__ **  Frequencies are just higher than UV Rays  It is strong enough to pass through many materials, including skin <span style="font: 7pt 'Times New Roman'; msofareastfontfamily: Symbol; msobidifontfamily: Symbol; msolist: Ignore;"> It also goes through clothes, shoes, and hair <span style="font: 7pt 'Times New Roman'; msofareastfontfamily: Symbol; msobidifontfamily: Symbol; msolist: Ignore;"> However, the bones absorb X-Rays; this is how X-Rays work

__ Gamma Rays __ ** <span style="font: 7pt 'Times New Roman'; msofareastfontfamily: Symbol; msobidifontfamily: Symbol; msolist: Ignore;"> Highest frequencies <span style="font: 7pt 'Times New Roman'; msofareastfontfamily: Symbol; msobidifontfamily: Symbol; msolist: Ignore;"> Shortest wavelengths <span style="font-size: 12pt; font-family: Cambria; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;"> λ <span style="font: 7pt 'Times New Roman'; msofareastfontfamily: Symbol; msobidifontfamily: Symbol; msolist: Ignore;"> Highest energy on the Electro-Magnetic Spectrum <span style="font: 7pt 'Times New Roman'; msofareastfontfamily: Symbol; msobidifontfamily: Symbol; msolist: Ignore;"> Radioactive materials and nuclear materials emit Gamma Rays
