Kinetics of surface deformations. Change in surface area upon switching the field on (a) and off (b), measured by the normalized change in scattering intensity, for field frequencies of 200, 300, 500 and 900 kHz. After an initial transient, the surface gradually expands (a) resp. contracts (b), exhibiting elastic ringing. Both the undulation frequency and final deformation amplitude increase with increasing field frequency. For clarity, the curves are offset vertically by multiples of 0.2. Inset: intensity structure function d2 versus lag time τ. In line with elastic recoil, d2 displays clear echoes (orange bullets), implying that the surface recurrently falls back to an earlier position. t − ton = 100 s is chosen as reference point
