The wave's energy is transferred to the substance, often increasing its internal energy, and the amount absorbed depends on the substance and wavelength.
The taking in of a wave by a surface or receiver, which can produce an observable effect such as a temperature rise or a signal detected.
Process in which infrared is taken in by a surface, increasing internal energy and warming the object.
