Terahertz to Millihertz 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.

A millihertz (mHz) is a unit of frequency equal to one thousandth of a hertz (0.001 Hz). It represents very low frequencies found in extremely slow oscillations, geological processes, and some biological rhythms.

The millihertz became necessary for describing extremely slow periodic phenomena in scientific research. It was particularly important in geophysics, astronomy, and biological studies where natural cycles occur over very long time periods.

Millihertz is used in geophysics for seismic wave analysis, astronomy for stellar oscillations, biological research for circadian rhythms, and precision timing applications. It's essential for measuring very slow natural cycles and long-period oscillations.
