WebSpherical wave fronts can be produced by a point source—a source whose dimensions are small compared with the distance to an observer. If waves travel outward in all directions … Webwavefronts of light. A wavefront is the locus of points which are the same optical distance from their source point. When light propagates in a homogeneous medium, equal optical distances are equal physical distances. Consequently, the wavefronts produced by a point source are perfect spheres because all points on a sphere are
