Unit+2+-+Quantum+Theory

-Quantum theory is the theory that energy is not continuous, but exists in small units called //quantum//.

**Electromagnetic Spectrum** -The term that defines the range of radiation that exists in our universe. -Different frequencies and wavelengths represent the characteristics of each wave. -Wavelength is the distance between successive points in the wave (from crest to crest). -Frequency defines the number of waves per second **(cycles per second or Hz**) -The idea that energy would be continuously emitted through the entire spectrum would mean you could get a wicked tan from operating a stove, and also be horribly killed from eventual x-ray and gamma ray poisoning. We all know this is untrue because when we turn on an element stove, all that is emitted is heat. For more information, refer to the Electron Configuration page.
