normal human eyes can see between 390nm to 700nm
no
nanometer range human i can see
Thank you for the invitation, but I will will leave this question to the experts answer.
A typical human eye will respond to wavelengths in air from about 380 to 750 nm.
Color Wavelength (nm)
UV higher Ferquency * 380 violet - 450 blue - 495 green - 570 yellow - 590 orange - 620 red - 750 IR Lower Ferquency
Color can be defined by particular wavelength(s) of light. A pure color will have one particular wavelength such as 450nm will appear as a vibrant blue. The nm stands for nanometer and is a measure of length. One nanometer is a billionth of a meter. The measurement is for one full light wave length.
