What is the definition of Wavefront?

1. A wavefront is the set of all locations in a medium where the wave is at the same phase.
2. This could be where all the crests are, where all the troughs are, or any phase in between.
3. Wavefronts are useful for showing how waves move in 2 dimensions. The length between two lines on a wavefront is exactly one wavelength.
4. The locus of all the points vibrating at the same phase is known as Wavefront.
5. The particles in the medium if it undergoes the same type of motion at a given moment of time which refers to the term Wavefront.
6. Depending on the shape of the formation of the locus of all points, Wavefront is classified particularly into the plane and spherical Wavefront.
