Far infrared ray is part of the sunlight spectrum that is invisible to the human eye.
The complete spectrum of sunlight consists of visible and invisible rays. The visible rays are red, orange, yellow, green, indigo, blue, and violet in color. The invisible rays are Ultra Violet, X-rays, Gamma, Cosmic, Microwave, Long Wave, Electrical Wave, and Infrared.
Electromagnetic waves between visible light and the microwave are called infrared waves. The wavelength of infrared waves range from 0.76 micron to 1,000 microns. This range is further subdivided into the ranges of Near, Medium, and Far-Infrared Rays with following wavelength: 0.76 to 1.5microns; 1.5 to 4 microns; and 4 to 1,000 microns respectively.
Far infrared waves are thermal. In other words, we experience this type of infrared radiation every day in the form of heat. Unlike ultraviolet light, FIR is harmless to the body.
