Webb7 apr. 2024 · Hint: A wavefront is defined as the locus of all points having the same phase at a given instant of time. The shape of the wavefront depends on the shape of the source of the disturbance. There are three types of wavefronts i.e., spherical wavefront, plane wavefront, and cylindrical wavefront. Complete step by step answer: WebbThe frequency-dependent factor a n(f) models the complex amplitude c n(f) and phase shift of the nth wavefront, i.e. a n(f) = c n(f)e j2ˇf ˝ n, where ˝ n is its Time-of-Arrival (ToA).
