  Scattering problems are the classical tools for modeling of light-matter
interaction. In this paper, we investigate the solution of dipole scattering
problem under different incident radiation. In particular, we compare the two
cases of incident plane and spherically incoming fields. With this comparison,
we disclose the two distinct groups of current-sourced and current-free
scattered fields which exhibit independent dynamics and dissimilar effects of
the scatterer. We demonstrate how these fields by interfering each other make
the resultant electric dipole moment of the scattered fields resonant and,
thus, give rise to all the spectral features observed in the classical solution
for dipole scattering of light.
