The amount of light a certain amount of water can absorb over time. Light absorption occurs when the production of energy is attained through absorbing light and converting it into energy. The light absorption is exactly related to the frequency of the light and object’s essence of atoms. If it is found to be complementary, then the light is fully absorbed. The energy is moved from spaces of radiation to a species that will absorb the light. The degree of energy that is needed form the light photon will be dependent upon the wavelength.
