Amplitude

the deviation from the mean, of whatever is being studied (displacement, pressure)

Human eye

the human eye is not capable of seeing radiation with wavelengths outside the visible spectrum. The visible colors from shortest to longest wavelength are red, orange, yellow, green, blue, violet
