Characteristic Behavior of Ion Acoustic Wave in A dusty Plasma

In this research, we make an attempt to derive theoretically 1-D linear dispersion relation of ion-acoustic waves in uniform unmagnetized dusty plasma valid in the long wavelength limits. This equation matched previously special equation of acoustic modes of a general form in magnetized dusty plasma. Depending on previous ly mentioned experimental data, we numerically consider various parameters that affect the properties of these waves in K+ dusty plasma. The study has shown that the presence of dus t grains is to modify the properties of ion acous tic waves and affect the behavior of the plasma in which they are immersed.
