spherical wave

The intensity of a spherical sound wave decreases in intensity at a rate of six decibels for each factor of two increase in distance from the source, as shown above. If the auditorium is flat, a hemispherical wave will result. Absorption of the diffracted wave by the floor or…

…expands in a series of spherical wavefronts. The fundamental mechanism for this propagation is known as Huygens’ principle, according to which every point on a wave is a source of spherical waves in its own right. The result is a Huygens’ wavelet construction, illustrated in Figure 2A and 2B for…
