Hello forum,
The reflectance spectrum has % on the vertical axis and wavelength on the horizontal axis.
A red object is red because it reflects all the red light and absorbs all the other wavelengths of the white incident light.
If the read object was ideal, would its reflectance spectrum be a delta at a specific wavelength and reflectance value 100%?
I guess the reflectance spectrum is obtained by scanning the reflected energy at each wavelength for incident white light.
Does the area under the reflectance function have value unity?
Some fluorescent substances have reflectance spectrum with values above 100%. What happens at those wavelengths?
Thanks,
Fog37
