Feb 27, 2016 · Conceptually we can talk about electromagnetic radiation based on its wave characteristics of velocity, amplitude, wavelength, and frequency. As previously stated, the velocity for all electromagnetic radiation is the same: 3 × 10 8 m/s. The amplitude refers to the maximum height of a wave. Wavelength Radiation is the transfer of heat by electromagnetic waves. When you stand in the sun, you are warmed by the electromagnetic waves, mainly infrared radiation (and to a lesser extent, visible light), that travels from the sun to Earth. In addition to the sun, light bulbs, irons, and toasters also transfer heat via radiation.
