Terahertz to Cycles per Second Converter

A terahertz (THz) is a unit of frequency equal to one trillion hertz (10¹² Hz). It represents extremely high frequencies typically found in infrared radiation, molecular vibrations, and advanced telecommunications research.

The terahertz became important with the development of advanced spectroscopy and telecommunications research in the late 20th century. It was particularly crucial for describing frequencies in the 'terahertz gap' between microwave and infrared radiation, opening new fields in materials science and medical imaging.

Terahertz frequencies are used in advanced spectroscopy, medical imaging, security scanning, materials research, and cutting-edge telecommunications. They're essential for terahertz imaging systems, molecular spectroscopy, and research into next-generation wireless communications.

Cycles per second (cps) is a unit of frequency representing the number of complete cycles of a periodic phenomenon occurring in one second. It's essentially equivalent to hertz but predates the modern SI terminology.

Cycles per second was the original term used to describe frequency before the adoption of the hertz in 1960. It was widely used in early electronics, radio, and physics literature, providing a descriptive term for periodic phenomena.

Cycles per second is rarely used in modern applications, having been replaced by hertz in scientific and technical contexts. It may still appear in historical literature, educational materials, or informal descriptions of frequency.
