Web7.1.2 Cylindrical Waves If a wave is emitted from a line source, the wavefronts are cylindrical. Since the wave expands to Þll a cylinder of radius r0, the wavefront crosses a cylindrical area that grows as Area =2πrh ∝ r. Therefore, since energy is conserved, the energy per unit area must decrease as r increases: E Area = constant = E ...

WebAccording to Huygen’s principle, all points on the wavefront will become secondary sources. As a result, the wavefronts will move forward. Wavelets are emitted by all secondary sources. The new position of the waveform is the tangent drawn to all of the wavelets. The waves spread out in all directions. WebThis refers to the spreading of sound energy as a result of the expansion of the wavefronts. Geometric spreading is independent of FREQUENCY and has a major effect in almost all sound propagation situations.
