We aim at studying the connections between the propagation of transverse waves on spicules and the small-scale magnetic reconnections at the feet of the spicules. The observed transverse wave may be interpreted as an Alfvén wave or a kink wave. We use the observations from SOT/Hinode in the Ca II H line to study the spicule dynamics above the reconnection sites. We found in three cases that the transverse oscillations were excited by magnetic reconnection, and steepened while propagating upwardly. In case-1, the steepening oscillations were attenuated at greater heights in association with the extension of the spicule plasma. In case-2, the transverse wave seems to be initiated by a footpoint jump of the spicule trace in the photosphere. The transverse wave in case-3 was found to be reflected, and then to propagate downward. These results reveal the wave dynamics in the low solar atmosphere, and provide observational evidence that is useful for the modeling of coronal heating and solar wind acceleration, involving wave generation by magnetic reconnection in the chromosphere.
