    The concept of wavefront is used to describe wave propagation.
    It is defined as the locus of all adjacent points at which the phase of vibration of a physical quantity associated with the wave is the same. That is, at any point, all points on a wave front are at the same part of the cycle of their variation.
    shape of wave front depends on the nature of the source of light. A point source has a spherical wave front, a parallel slit has a cylindrical wave front and a parallel beam of light has plane wave front.
