Fig. 4.

The distributions of the incident (red dashed line), scattered (blue dotted line), and total (black solid line) pressures over the rigid sphere, plotted as a function of polar angle $\mathit{\theta }$, for fixed $\mathit{kR}=4.0$. (a) is for the $\cos \mathit{\omega }\mathit{t}$ component while (b) is for the $\sin \mathit{\omega }\mathit{t}$ component.
