terahertz
Between microwave, infrared
Terahertz refers to a unit of frequency equal to one trillion hertz, or cycles per second.
The terahertz range lies between microwave and infrared on the electromagnetic spectrum.
Terahertz radiation can penetrate many materials opaque to visible light, making it useful for security scanning and medical imaging: terahertz imaging, terahertz spectroscopy.
