Question

How does wavefront division provide coherent sources?

Short/Brief Note
Advertisements

Solution

  1. Wavefront division is the most commonly used method for producing two coherent sources.
  2. A point source produces spherical wavefronts. All the points on the wavefront are at the same phase.
  3. If two points are chosen on the wavefront by using a double slit, the two points will act as coherent sources.
