Consider the UV-Visible light of intensity, I ₀ , traversing through an aqueous solution of an organic compound placed in a cuvette of length d cm . The compound absorbs UV-Visible light, and hence the intensity of the light emerging out of the cuvette (also called as the transmitted light) reduces to I (with I I ₀ ). The magnitude of the reduction of the intensity of the transmitted light depends on the wavelength o
