Answer» wavefront is termed as the locus of all the points joining together woth same phase, a line or curve in 2dimensional wheras a wavelet is defined as: a wave like oscillation with ampliyude expanding and contracting gradually and sequentially. the locus of all the points of the medium which receives disturbances simoultaneously and are in same state of vibration are called as wavefront .every point on a wavefront act as a new source called as secondary wavelets .wavelets are just a kind of daughter wave u can say .more precisely , wavelets is small wave like oscillation , which starts with zero displacement , increase to max . displacement , then decrease to zero again .

Answer»

wavefront is termed as the locus of all the points joining together woth same phase, a line or curve in 2dimensional

wheras a wavelet is defined as: a wave like oscillation with ampliyude expanding and contracting gradually and sequentially.

the locus of all the points of the medium which receives disturbances simoultaneously and are in same state of vibration are called as wavefront .every point on a wavefront act as a new source called as secondary wavelets .wavelets are just a kind of daughter wave u can say .more precisely , wavelets is small wave like oscillation , which starts with zero displacement , increase to max . displacement , then decrease to zero again .
