Terahertz (THz) is a unit of measure of frequency that is equal to 1 trillion hertz (1012 Hz) . It usually refers to the frequency of an electromagnetic wave, which is a part of the electromagnetic spectrum invisible to the naked eye that lies in between the microwave and the infrared range.
Read moreWhat is THz wavelength?
Between microwaves & infrared The terahertz range refers to electromagnetic waves with frequencies between 100 GHz and 10 THz, or wavelengths between 3 mm and 30 μm . Light between radio waves and infrared has some unique properties. Terahertz can “look inside” plastics and textiles, paper and cardboard.

Frequency of Light The visible light frequency is 400 THz to 700 THz , approximately. A THz is a Terahertz, which is a unit of frequency equal to one trillion Hertz. The electromagnetic spectrum. The frequency increases as we move to the right.16 Eyl 2021
Read moreWhat uses low frequency radio waves?
Because low frequency waves travel globally, they have practical uses. Long before GPS existed, engineers used low frequency waves broadcast from radio stations to determine location anywhere on the planet . And various navies have been using low frequency waves to communicate with submarines across an entire ocean.
Read moreWhat are low and medium frequency radio waves used for?
Frequencies immediately below MF are denoted low frequency (LF), while the first band of higher frequencies is known as high frequency (HF). MF is mostly used for AM radio broadcasting, navigational radio beacons, maritime ship-to-shore communication, and transoceanic air traffic control .
