Web7 apr. 2024 · Origin of Emission and Absorption Process. In the mid 19th century, scientists found that, when the materials are heated in flames or kept in electrical discharge, the lights are emitted with well-defined frequencies. The study of emission and absorption spectra of atoms plays a predominant role in developing the atomic structure. Web9 sep. 2024 · Light passing through a sample solution will partially be absorbed by molecules present in the sample. The amount of light unable to pass through a sample is measured as the absorbance value. Absorbance is directly proportional to the concentration of the molecules and is measured on a logarithmic scale from 0 to infinity.
