The Beer-Lamberts Law of Light Absorption

The higher the s value, higher will be the intensity of the absorption. Usually the intensity of light absorption is high for allowed electronic transition process and low for forbidden transition process.

The penetration of visible light through foamed polystyrene has been shown to foUow approximately the Beer-Lambert law of light absorption (22). This behavior presumably is characteristic of other ceUular polymers as weU. 

Example 3.2 Atmospheric Heating Rates The Chapman Function The nature of the attenuation that occurs as radiation penetrates the atmosphere can be seen by considering the Beer-Lambert law of light absorption for a single absorbing component. 

The Beer-Lambert law of light absorption states that the fraction of the incident light absorbed is proportional to the number of molecules, the length of the light path, and a proportionality factor ...
