This means that they have to have some sort of matter to travel through.]]> 2016-12-19 18:20:53 UTC https://padlet.com/1539223/3byssey94fst/wish/144364596 1539223 https://padlet.com/1539223/3byssey94fst/wish/144365064 Electromagnetic waves are waves that can travel through a vacuum (empty space).

They range from around a foot long to several miles long. Radio waves are often used to transmit data and have been used for all sorts of applications including radio, satellites, radar, and computer networks. ]]> 2016-12-19 18:28:56 UTC https://padlet.com/1539223/3byssey94fst/wish/144366393 1539223 https://padlet.com/1539223/3byssey94fst/wish/144366763 Microwaves are shorter than radio waves with wavelengths measured in centimeters.

At this point in the electromagnetic spectrum, scientists begin to think of these rays more as particles than waves.

Gamma rays are the shortest waves in the spectrum and, as a result, have the most energy.
