Energy leaves a source, travels as a wave with nothing material moving between them, and is transferred to a store in the absorber.
The place the wave transfers energy from and the place it transfers energy to, such as the Sun and your skin.
The source emits the wave, the wave travels through a vacuum or a medium, and the absorber gains the energy.
