Infrared (ir) radiation is a specific form of electromagnetic radiation, which is a form of energy that travels as a wave with a given frequency (number of waves in a certain time) and wavelength (distance between two wave-tops) that can be absorbed or emitted by matter. Scientists discovered much of what we know about the structure of the atom by observing the interaction of atoms with various forms of radiant, or transmitted, energy, such as the energy associated with the visible light we detect with our eyes, the infrared radiation we feel as heat, the. Infrared radiation is a type of electromagnetic radiation, as are radio waves, ultraviolet radiation, x-rays and microwaves infrared (ir) light is the part of the em spectrum that people encounter most in everyday life, although much of it goes unnoticed.
