Fig. 7: Comparison of shadow area change for modes 2, 3, and 4 as a function of deformation amplitude.

The dimensionless shadow areas (\(A/(\pi {R}_{0}^{2})\)) are calculated using the analytical spherical harmonics of the droplet with superimposed mode 2, mode 3, mode 4 functions at varying amplitudes a_n with volume constrained to \(\frac{4}{3}\pi {R}_{0}^{3}\).
