Most humans eyes are sensitive to wavelengths between about 400 nm (violet) and 700 nm (red)
Frequencies in the range 30 PHz (PetaHertz) to 750 THz (TeraHertz), Wavelengths from 10 nm to 400 nm.
Frequencies in the range 30 PHz (PetaHertz) to 750 THz (TeraHertz), Wavelengths from 10 nm to 400 nm.
Approx. 350 nm.
Visible light wavelengths fill the electromagnetic spectrum between red wavelengths and violet wavelengths.
A typical human eye will respond to wavelengths from about 390 to 750 nm. In terms of frequency, this corresponds to a band in the vicinity of 400-790 THz
375 to 750 nm
We refer to this portion as "visible light," which has wavelengths between 390 nm and 700 nm.
Most humans eyes are sensitive to wavelengths between about 400 nm (violet) and 700 nm (red)
Any whose wavelength does not exceed 379 nm.
The range of wavelengths for infrared radiation is beween 700 nm and 10e6 nm.
It will be a dark red solution- like liquid bromine
Human eyes are not sensible to these radiations.
380 to 750 nm
- Long wavelengths - Mid-size wavelengths - Short wavelengths The reddish colors are the long wavelengths, the mid-size wavelengths are the greenish colors and the short wavelengths are the bluish colors.
750 nm
430 nm and 662nm. novanet
