FIGURE Q16.9 shows the wavefronts of a circular wave. What is the phase difference between

(a) points A and B,

(b) points C and D, and

(c) points E and F?

a) The phase difference between A and B is zero.

b) The phase difference between points C and D is 4π radians

c) The phase difference between points E and F is π radians

The wavefronts of a circular wave with different points are given in the diagram

It is the locus of all the points which are having the same phase

The phase difference between adjacent wavefronts is 2π radians

- The phase difference between A and B is zero because, both the points are on the same wave front. Therefore, A and B are having the same phase.
- The phase difference between points C and D is 4π radians as they are having one wave front between them
- The phase difference between E and F is π radians as their wave fronts are adjacent to each other.
