| Abstract: | The angular dispersion of rainbow and secondary rainbow is studied,and their comparison are made between the angular dispersion of a spherical raindrop and that of a water triangular prism.The results indicate that their formulae of angular dispersion are same,and in value the angular dispersion of secondary rainbow is bigger and the dispersion of the spherical raindrop to light is stronger than that of water triangular prism. |

| Keywords: | rainbow secondary rainbow angular dispersion the angular dispersion formulae |
