Question

the group of wavelets is called wavefront.​

Answer 1

Explanation:

In physics the wavefront of a time-varying field is the set (locus) of all points where the wave has the same phase of the sinusoid.[1] The term is generally meaningful only for fields that, at each point, vary sinusoidally in time with a single temporal frequency (otherwise the phase is not well defined).

Wavefronts usually move with time. For waves propagating in an unidimensional medium, the wavefronts are usually single points; they are curves in a two dimensional medium, and surfaces in a three-dimensional one.
