WebThe Beer–Lambert law, also known as Beer's law, the Lambert–Beer law, or the Beer–Lambert–Bouguer law relates the attenuation of light to the properties of the material through which the light is travelling. The law is commonly applied to chemical analysis measurements and used in understanding attenuation in physical optics, for photons, … WebLambert’s law was extended by beer who showed that when light passes through a solution of a given thickness the fraction of incident light absorbed is dependent not only on the intensity I of light but also on the concentration c of the solution. This is known as the Beer’slaw.-𝑑𝐼 𝑑𝑥 ∝ --- --- --- --- --- ---(8)
