9th Electromagnetic Spectrum Its more used on every day things
like microwave, tv, radio, etc. Description it's kinda like static when a baloon sticks to a wall or your hair standing up Sites http://science.hq.nasa.gov/kids/imagers/ems/waves3.html http://science.hq.nasa.gov/kids/imagers/ems/ems.html This visible part of the electromagnetic spectrum consists of the colors that we see in a rainbow from reds and oranges, through blues and purples colors actually corresponds to a different wavelength of light electromagnetic spectrum
the entire spectrum, considered as a continuum, of all kinds of electric, magnetic, and visible radiation, from gamma rays having a wavelength of 0.001 angstrom to long waves having a wavelength of more than 1 million km.
Raidio waves Radio waves have the longest wavelengths in the electromagnetic spectrum These waves can be longer than a football field or as short as a football they also carry signals for your television and cellular phones http://dictionary.reference.com/browse/electromagnetic+spectrum The antennae on your television set receive the signal, in the form of electromagnetic waves TV Cable companies have antennae or dishes which receive waves broadcasted from your local TV stations The signal is then sent through a cable to your house Microwaves infrared visible light ultraviolet light xrays Microwaves have wavelengths that can be measured in centimeters The longer microwaves, those closer to a foot in length, are the waves which heat our food in a microwave oven Microwaves are good for transmitting information from one place to another because microwave energy can penetrate haze, light rain and snow, clouds, and smoke microwave [mahy-kroh-weyv] Show IPA noun, verb,-waved, -waving.
an electromagnetic wave of extremely high frequency, 1 GH3 or more, and having wavelengths of from 1 mm to 30 cm.

microwave oven. Infrared light lies between the visible and microwave portions of the electromagnetic spectrum Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet Shorter, near infrared waves are not hot at all - in fact you cannot even feel them. These shorter wavelengths are the ones used by your TV's remote control. 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.
Red has the longest wavelength and violet has the shortest wavelength.
When all the waves are seen together, they make white light. Ultraviolet (UV) light has shorter wavelengths than visible light Though these waves are invisible to the human eye, some insects, like bumblebees, can see them Scientists have divided the ultraviolet part of the spectrum into three regions: the near ultraviolet, the far ultraviolet, and the extreme ultraviolet The three regions are distinguished by how energetic the ultraviolet radiation is, and by the "wavelength" of the ultraviolet light, which is related to energy. As the wavelengths of light decrease, they increase in energy X-rays have smaller wavelengths and therefore higher energy than ultraviolet waves It is also because X-ray light tends to act more like a particle than a wave
