What is the term for energy transfer by electromagnetic waves?

Explanation:
Energy transfer by electromagnetic waves is called radiation. It moves energy through space using waves of light and infrared energy, so heat can travel from a hot surface to a cooler one even without touching. Conduction transfers heat through direct contact or through a solid by molecular interactions. Convection transfers heat by the bulk motion of a fluid, like warm air rising. Evaporation is a phase change where liquid becomes gas at the surface, driven by heat but not a heat-transfer mode itself. So radiation is the term that describes energy transfer by electromagnetic waves.
