Abstract
This paper introduces a method of finding the state of precise minimum deviation,measureing the angle of minimum deviation by spectrometer. We measured the top angle of triangular prism, and the different angles of minimum deviation according to different monochromatic light traveling through the prism, then calculated the refractive index of prism. In the visible light area, the refractive index depending on light wavelength was in accordance with Cauchy′s dispersion formula.
