What is the wavelength range of Far-Infrared light?

The wavelength range of Far-Infrared light is indeed from 1,500 to 12,500 nanometers (nm). This range encompasses wavelengths that are longer than those of the mid-infrared spectrum but shorter than the microwave range, placing Far-Infrared light in the electromagnetic spectrum in a specific position.

Understanding these ranges is essential in various fields, including physics and medicine. For instance, in therapeutic applications, Far-Infrared light is often used for its ability to penetrate tissues more deeply than shorter wavelengths, providing benefits in heating and promoting circulation within the body.

Each specified range in the other choices falls outside the typical designation for Far-Infrared light, which helps clarify the boundaries of this aspect of the electromagnetic spectrum.
