WebOne such wavefront is a spherical wavefront. Lightwave amplitude, A ∝ 1/r. Light waves intensity, I ∝ 1/r2. Cylindrical Wave Front; All locations equidistant from a linear source lie on the surface of a cylinder when the source of light is linear. A cylindrical wavefront is the name for such a wavefront. Plane Wave Front WebCylindrical wavefront. The wavefronts are cylindrical in shape when the light source is linear. The source is equidistant from all of the places. Plane wavefront. The wavefronts of light originating from a very far-away source are flat. Because the amplitude of a plane wavefront remains constant, the intensity of the wavefront stays unchanged.
