The first question is not as simple as it sounds. Light from a point source travels in expanding spherical waves. Light from a line source has cylindrical geometry. There are sources, such as lasers, giving plane waves. Huygens showed that the various kinds of wavefronts could be constructed assuming that each point of a wave produces an expanding spherical wave front and they then combine to form various types.
