Abstract
Critical-angle measurements of the refractive index of dilute dye solutions are presented. These provide experimental support for a recent theoretical assertion that optical absorption in a refractometric sample can give rise to large errors in critical-angle measurements of refractive index. The error in the transmission mode is shown to be much larger than the corresponding reflection mode error.Keywords
