"THz" stands for "terahertz", a unit of frequency.
1 THz = 1 trillion hertz = 1,000 GHz = 1,000,000 MHz = 1,000,000,000 KHz
For a normal human being, visible light comprises electromagnetic radiation with wavelength in the range in the 390 nanometres (frequency = 770 THz) to 700 nm (430 THz).
UVA, 750 THz to 950 THzUVB, 950 THz to 1.07 PHzUVC, 1.07 PHz to 3 PHzUVE, 3 PHz to 30 PHz
Red is about 405 to 480 THz Orange from 480 to 515 THz Yellow from 515 to 525 THz Green from 525 to 575 THz Cyan from 575 to 610 THz Blue from 610 to 680 THz Violet from 680 to 785 Tz
Visible light has a lower frequency than infrared radiation. Visible light ranges in frequency from approximately 430 THz (red light) to 750 THz (violet light), while infrared radiation has frequencies below 430 THz.
The period of visible light ranges from approximately 400 nanometers to 700 nanometers in wavelength. This corresponds to frequencies of about 430 THz to 750 THz. Beyond these limits, light is either in the ultraviolet or infrared spectrum.
There are 7 different types of visible light violet: 668-789 THz indigo: 668-714 THz blue: 606-668 THz green: 526-606 THz yellow: 508-526 THz orange: 484-508 THz red: 400-484 THz 1THz = 10^3 GHz = 10^6 MHz = 10^3 kHz = 10^12 Hz
The frequency ranges between 450 THz and 950 THz.

THz stands for Tera-Hertz which is equivalent to 10^12 Hertz (cycles per second).
No. I'm currently using electrical tape to block radiation at 1300 nm and transmit THz radiation from 0.1-3 THz. The spectrum of the THz radiation is only mildly modified vs using silicon as a filter and electrical tape has similar transmission to silicon.
From Red about 780 nm (380 THz) to Violet about 400 nm (750 THz)
The frequency range for visible light is 400-790 THz
All colors of the visible light spectrum are electromagnetic waves. From a physics point of view, the only difference between each of the colors are their frequencies (and therefore wavelengths). Color --> Wavelength --> Frequency ----------------------------------------------- violet --> 380 - 450 nm --> 668-789 THz blue --> 450 - 495 nm --> 606-668 THz green --> 495 - 570 nm --> 526 - 606 THz yellow --> 570 - 590 nm --> 508 - 526 THz orange --> 590 - 620 nm --> 484 - 508 THz red --> 620 - 750 nm --> 400-484 THz where 1 nm = 10-9 m and 1 THz = 1012 Hz.
