PRESENTATION OUTLINE
THE ELECTROMAGNETIC SPECTRUM
THE RANGE OF WAVELENGTHS OR FREQUENCIES OVER WHICH ELECTROMAGNETIC RADIATION EXTENDS.

The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation.[4] The "electromagnetic spectrum" of an object has a different meaning, and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object.

Energy
In physics, energy is a property of objects, transferable among them via fundamental interactions, which can be converted in form but not created or destroyed.

Wavelength
In physics, the wavelength of a sinusoidal wave is the spatial period of the wave—the distance over which the wave's shape repeats.

Frequency
The rate at which something occurs or is repeated over a particular period of time or in a given sample.

Colors of light
White light is all colors combined in the spectrum. Black light is the absence of color. Blue light has high frequency and red light has low frequency.

EXPERIMENT
- Get a slinky and have 2 people hold opposite ends
- Snap the slinky so that it makes a wave
- The faster you do it the higher the frequency
- The harder you do it the higher the wavelength
