Abstract
This paper describes a simple method of measuring refractive indices of liquids. The basic element is a thin wedge cell and the source of light is a low power HeNe laser. Conditions are derived, to obtain the best possible accuracy using this setup. Some applications of this method are suggested.Keywords
