Abstract: Based on the existing theory, the refractive index of eight spectrums for mercury spectrum is ob- tained by a dispersion experiment. The empirical formula of dispersion function for wavelength and refractive index is presented by the polynomial fitted and the angular dispersion of mercury spectrum is also obtained. This is bene- ficial to people understanding dispersion further.
