Question

what is the cylindrical wave front

Answer 1

Cylindrical Waves. in the limit . Here, is the amplitude of the wave. The associated wavefronts (i.e., the surfaces of constant phase) are a set of concentric cylinders that propagate radially outward, from their common axis ( ), at the phase velocity .

Answer 2

Ocean waves approaching a beach - plane wavefront. Waves radiating outward when a stone is dropped in water - circular wavefront.

Water surface being 2 dimensional, above example is missing one physical dimension wrt light or sound. But you can extend the idea.
