Speed of a wave equation
Electromagnetic radiation is the emmision of energy in the form of electromagnetic waves. They are transverse waves. For an electromagnetic wave, c, the speed of light replaces u. All electromagnetic radiation travels at 3.0 x 108 m/s and that is the fastest speed there is.
