So what is an electromagnetic wave anyway?
| This
electromagnetic spectrum shows the many different
kinds of electromagnetic waves that are around us.
Everything from ultraviolet to radio waves can be
harvested. Undergraduate engineering students at Duke university were able to create a harvester that could conserve 37% of lost microwaves. This amount of energy is comparable to that of what solar cells are able to get from ultraviolet waves.  http://www.eurekalert.org/multimedia/pub/64439.php?from=253569 |

All electromagnetic
waves are made up of three main components:

The frequency of a wave can be
further broken down into the quotient of the speed of
light (c) and the wavelength (). |
