A Wave Phenomenon. Electromagnetic radiation travels as a transverse wave. The basic parts of any wave include the wavelength, frequency, amplitude, wave speed. See the following site for information about the wave nature of electromagnetic radiation. Electromagnetic Radiation And Energy.
Electromagnetic waves carry energy through space and time.
The energy of the wave is directly related to its frequency. See the following sites for a more complete explanation. See the figure below. Solar Irradiation Radiation is the means of transferring energy through space. The transfer of energy by radiation is given by the Stefan Boltsmann law.
