What is the narrow band of light waves that humans can see?
The optical band, from around 400 Thz to 800 Thz.
What does the frequency of light determine?
It can determine a lot of different things. You can determine the wavelength of the light wave from the frequency and the speed: wavelength = (speed)/(frequency). Speed of light is approximately 3 x 108 m/s. The energy of the photons can be determined by the frequency: Energy of a photon = h * frequency; h is Planck's constant = 6.626 x 10-34 Joule*sec. Higher frequency waves are sometimes called high-energy waves (X-rays, gamma rays for example) Different frequencies of visible light will be different colors. Red has the lowest frequency of the visible spectrum, and violet is the highest frequency. Note that each color is not a specific frequency, but a range of frequencies, with the color shifting as frequency gradually changes. Red: 400 to 484 THz (TeraHertz or 1012 Hertz) Orange: 484 to 508 THz Yellow: 508 to 526 THz Green: 526 to 606 THz Cyan: 606 to 630 THz Blue: 631 to 668 THz Violet: 668 to 789 THz See Related Links (Wikipedia & Wolfram ScienceWorld)
What is the frequency for green light?
The range is 526-606 THz.
How do THz's harm people?
Basically, they don't. THz waves are light at very low energies. Much too low in energy to break any chemical bonds -- they about a 1000 times lower energy than the ionization threshold for stripping electrons off atoms. Some very specific THz frequencies can resonate with vibrations of atoms within molecules, but to directly cause enough vibrations to actually heat and therefore damage a person's molecules would require a very high power, very focused, and very specific frequency emitter. Broad band THz emitters (such as the THz light from the heat of every object around us) will not harm people.
Frequency for UV waves?
The frequency ranges between 450 THz and 950 THz.
Is red a higher frequency color of visible light in the electromagnetic spectrum?
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
What kind of wave does each color of visible light have?
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.
What is the frequency of visable light?
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
Which type of radiation can we see?
Visible Light - 430 THz to 790 THz
What is the frequence of uv?
The frequency ranges between 450 THz and 950 THz.
What is the measurement THz?
"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
What does THz stand for?
THz stands for Tera-Hertz which is equivalent to 10^12 Hertz (cycles per second).

Does electrical tape stop thz radiation?
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.
The visible portion of the electromagnetic spectrum extends from what?
From Red about 780 nm (380 THz) to Violet about 400 nm (750 THz)
A light is emitted from a laser.its frequency is 630THz.what is the wavelength and color?
You can get the wavelength by dividing the speed of light by the frequency. Don't forget that THz means 10 to the power 12 Hz.
