At any given time, the common tangent on the wavelets in the forward direction gives the new wavefront. The wavefront is the sum of the spherical wavelets. chiropractor reading

"WebThe basic principle underlying the method is that a wavefront can be evolved by repeated application of local ray tracing from a set of points lying on the wavefront surface. Thus, for some given time step δt, a new wavefront is deﬁned by the end points of the rays traced from the old wavefront, as illustrated schematically in Fig. 28. " - Ray and wavefront
