| Abstract: | By using the reductive perturbation technique, we obtained a nonlinear Schrodinger equation for dust acoustic waves in dusty plasma with many different dust grains. The modulational instability of dust acoustic waves is also studied when the dust size distribution is given by power law distribution. |

| Keywords: | dust acoustic waves power law distribution modulational instability |
