Abstract: In this article, we describe a simple optics-based non-destructive experimental technique devised with the necessary background theoretical formulation to study the liquid properties like surface tension and surface capillary wave profile like wavelength and phase velocity of pure and impure water. Experimentally, we have estimated the surface tension of pure water using this optical method is (73.6+ 1.5) dyne/cm. We have also studied the variation of surface tension of water with adding organic and inorganic impurities using this same method. Finally we estimate the wavelength and phase velocity of capillary wave using the measured values of surface tensions of the above liquids.
