For the color Green, explain the relationship between the observed color and either the wavelengths of maximum absorbance or maximum transmittance.
Solution :-
The relationship between the observed color and either the wavelength of maximum absorbance is that when white light passes through or is reflected by a colored substance, a characteristic portion of the mixed wavelengths is absorbed. The remaining light will then assume the complementary color to the wavelength(s) absorbed. This relationship is demonstrated by the color wheel shown on the right.
The color of an object or material is determined by the wavelengths it absorbs and those it reflects. An object has the color of the wavelengths it reflects. A material that reflects all wavelengths of visible light appears white. A material that absorbs all wavelengths of visible light appears black. A green lime absorbs most wavelengths but reflects green, so the lime looks green.
