Electromagnetic+Radiation

=Electromagnetic Radiation=

Electromagnetic Radiation is radiation that exhibits wave properties and qualities as it travels through space

Waves
There are several key terms that we will be discussing regarding waves.

The ** crest ** is the highest point of a wave. The ** trough ** is the lowest point of a wave. The ** wavelength ** is the distance between two points on adjacent waves. ** Wavelength ** is most commonly measured from the crest of one wave to the crest of the next wave or from the trough of one wave to the trough of another wave. However, ** wavelength **can be measured from any two corresponding points on adjacent waves. Because ** wavelength ** is so small, it is typically measure in nanometers (nm) The ** amplitude ** is the distance from the midline to the crest or from the midline to the trough.

Finally, ** frequency ** is a measurement of the number of waves that pass through a point in a given amount of time. Typically, **frequency** is measured in inverse seconds, showing the number of waves that pass through a given point in space in one second time.

Check out this website for more information on waves. Be sure to try the **frequency** simulator listed in the frequency section of the webpage. Wave Parts Website
