DEFINITION

Classification: 264/481

Infrared radiation:

(under subclass 479) Processes wherein the energy applied is considered to have a frequency range with wavelengths longer than those of visible light and shorter than those of radio waves.

(1) Note. Wave energy measured using the electromagnetic spectrum, having a portion which is visible to the eye, lying between wavelengths of 750 nm (0.75 micrometers) and about 1 mm (1000 micrometers) are properly classified here as infrared.
