Terahertz radiation

Range 300-3000 GHz of the electromagnetic spectrum

Terahertz radiation – also known as terahertz waves, tremendously high frequency (THF), T-rays, T-waves, T-light, or T-lux– consists of electromagnetic waves within the frequency band from 0.1 to 10 terahertz (symbol THz), as designated by the International Telecommunication Union (ITU). One terahertz is 1012 Hz or 1,000 GHz. Wavelengths of terahertz radiation range from 3 millimeters and 30 micrometers (3 mm = 3000 μm to 30 μm), sometimes known as the submillimeter band, and its radiation as submillimeter waves, especially in astronomy.
