Zusammenfassung

We use diffusing wave spectroscopy to study the microscopic dynamics of foams. These foams are lev-itated diamagnetically, such that very high liquid fractions can be achieved. We find that at low liquidfraction the dynamics is dominated by local rearrangements, whereas at high liquid fraction the move-ment of bubbles is ballistic and large scale rearrangements are absent. This change in the microscopicdynamics coincides with a change in the scaling of coarsening on increasing the liquid fraction that wehave found earlier.
