Query: How capillarity affects the propagation of elastic waves in soft gels   Elastic waves propagating at the interface of soft solids can be altered by
the presence of external forces such as capillarity or gravity. We measure the
dispersion relation of waves at the free surface of agarose gels with great
accuracy, revealing the existence of multiple modes as well as an apparent
dispersion. We disentangle the role of capillarity and elasticity by
considering the 3D nature of mechanical waves, achieving quantitative agreement
between theoretical predictions and experiments. Notably, our results show that
capillarity plays an important role for wavenumbers much smaller than expected
from balancing elastic and capillary forces. We further confirm the efficiency
of our approach by including the effect of gravity in our predictions and
quantitatively comparing it to experiments.
