Question

What is a wave front diagram?

Answer 1

1. A wave front diagram is a simple way to demonstrate the waves and to see how these waves are moving.
2. A wavefront is the set of all locations in a medium where the wave is at the same phase
3. A wavefront is an imaginary surface representing corresponding points of a wave that vibrate in unison.
4. If the propagation speed differs at various points of a wavefront, the orientation and shape of the wavefronts may differ by refraction.
5. Particularly, lenses can alter the wavefront optical shape from spherical to planar, or vice versa.
6. The types of wavefront:
   9.1 spherical wavefront
   9.2 cylindrical wavefront
   9.3 plane wavefront
