Question

What is the phase difference between two points on a wavefront?

Answer 1

The phase difference between two points on a wavefront:

1. A surface over which the phase of the wave is constant is known as a wavefront.
2. There is zero phase difference between two points on a wavefront.
3. The reason for zero is the locus of the neighboring particles of the medium vibrating in the same phase.
4. The phase difference between two waves is defined as the difference in phase angle.
