Radiation is defined as what?

Explanation:
Energy transfer by electromagnetic waves is how radiation works. This means energy can move across space without needing a medium, so heat from the Sun travels through the vacuum of space to reach Earth. Conduction needs direct contact between substances, convection involves moving fluids, and sublimation is a phase change, not a method of heat transfer. So the defining idea of radiation is the transfer of energy via electromagnetic waves.
