Explanation:
When a substance or chemical specie accepts a proton then an acid is formed. Whereas is a substance or chemical specie tends to lose a proton then a base is formed.
Chemical formula of amino group is 
and it is able to lose a proton to form R-NH-R'. When it tends to gain a proton the it form R-NH_{3} compound.
Chemical formula of carboxylic group is -COOH. When it loses a proton it forms 
ion and whenit gains an electron then it forms 
.
Therefore, we can conclude that the amino and carboxyl functional groups tend to form bases and acids by attracting or dropping a proton.
This is related to the energy carried by photons of light the energy of each photon is proportional to the frequency of the light since red light has a lower frequency then violet light and photons of red light carry less energy than the photons of violet light as a result the red protons eject electrons that have less energy than the ejected electrons by Violet photons
