Answer to Question #259897 in Electrical Engineering for Anwesha Datta

Question

Explain the principles of spectroscopy with emphasis on Electromagnetic Spectrum Table.

Answer 1

The principal of spectroscopy is based on Lamberts and Beer’s law of photo-chemistry. The transmitted light coming out of a liquid contained in a transparent glass depends upon the concentration (C), path length (T) and intensity of the incident light. If path length T and intensity of the incident light are kept constant, the transmitted light intensity will be proportional to the concentration of the liquid contained in glass chamber. Spectroscopy employes visible range electromagnetic radiation in the wavelength range from 300 nm to 700 nm.
