What is another word for terahertz?
Pronunciation: [tˈɛɹəhˌɜːts] (IPA) 
Terahertz refers to the frequency range between one trillion and 100 gigahertz, which is often used in advanced technologies such as imaging and communication systems. However, there are other synonyms that can be used to refer to similar concepts, such as sub-millimeter radiation, far-infrared radiation, and THz radiation. Sub-millimeter radiation implies the wavelength of the radiation, while far-infrared radiation refers to the lower end of the infrared region of the electromagnetic spectrum. THz radiation is often used interchangeably with terahertz, particularly in reference to the study of the properties of materials and biological systems in the terahertz frequency range.
