Unit THz
Name terahertz
Category Frequency
Details Terahertz (THz) is a unit of frequency in the field of electromagnetic waves or radiation. It is defined as one trillion hertz (10^12 Hz). Hertz (Hz) is the standard unit of frequency, representing the number of cycles per second. Therefore, one terahertz refers to one trillion cycles per second. Terahertz waves fall within the range between microwaves and infrared light in the electromagnetic spectrum, with frequencies typically ranging from 0.1 THz to 10 THz. Terahertz radiation is used in various applications, such as imaging, communication, and sensing, due to its unique properties like being non-ionizing and having the ability to penetrate through materials like clothing, paper, and plastic.
