Total internal re ection technique is examined critically for the measurement of apex angle of the prism. Recognition of the critical boundary completely speciÿes the apex angle 'A' of the prism by keeping constant the ratio of refractive index of sample uid (n1 = 1:4) to that of glass (n2 = 1:7). R
