MCQ
The wavefront is a surface in which:
  • A
    All points are in the same phase.
  • B
    There is a pair of points in opposite phase.
  • C
    There is a pair of points with phase difference $(\frac{\pi}{2})$.
  • D
    There is no relation between the phases.

Answer

  1. All points are in the same phase.

Explanation:

A wavefront is the locus of points characterized by propagation of position of the same phase:

a propagation of a line in 1D, a curve in 2D or a surface for a wave in 3D.
