Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. [4] Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle ...
