Abstract

This paper describes a simple technique for determining the surface tension of the liquids, based on laser light diffraction on capillary waves. Capillary waves of given frequency are created by an exciter needle acting on the surface of liquid which acts as a reflection grating, the constant of which(the wavelength of capillary waves) can be determined based on unknown incidence angle of light(grazing angle). This technique permitted accurate measurement of the spot and eliminates most of the fluctuations due to vibration. The surface tension of liquids are calculated by applying the dispersion relation for capillary waves and analyze the difficulties that will arise when setting up and conducting the experiment in detail. It also reports the refractive index liquids in the visible region by an Abbe’s refractometer.

Key Words

Surface tension, Coefficient of viscosity of liquid, Refractive Index of liquids
