Question

The phase diference between any two points situated on the same wavefront is

Answer 1

The phase diference between any two points situated on the same wavefront is zero.

First of all, what is WAVEFRONT ?

• Wavefront is a term extensively used in study of wave optics.

• Now, wavefront is defined as the locus of all those vibrating particles of a wave oscillating in the same phase.

• As the definition states , all the particles in a wavefront have the same phase and hence the phase difference between them will be zero.

• Wavefront is usually found placed perpendicular to the direction of propagation of the wave.

Lets discuss about a few wavefronts :

• For a point source we get to see spherical wavefronts at various radii.

• For a line source we get to see cylindrical wavefronts at various radii.

• For sources placed at infinity we get plane wavefronts at various distances.
