The electrostatic force between two large charged bodies kept at a small distance $x$ apart.
As a wave propagates (a) the wave intensity remains constant for a plane wave. (b) the wave intensity decreases as the inverse of the distance from the source for a spherical wave. (c) the wave intensity decreases as the inverse square of the distance from the source for a spherical wave. (d) total intensity of the spherical wave over the spherical surface centered at the sources remains constant at all the times.
