Compression or shear waves
WebDec 7, 1998 · The wave theory is combined with a model of the mechanical properties of marine sediments to yield expressions relating the compressional and shear wave speeds to the grain size, the porosity, and the density of the medium. These expressions show compelling agreement with a number of measurements from the literature, representing … WebSep 12, 2024 · A speaker produces a sound wave by oscillating a cone, causing vibrations of air molecules. In Figure 17.2. 2, a speaker vibrates at a constant frequency and amplitude, producing vibrations in the surrounding air molecules. As the speaker oscillates back and forth, it transfers energy to the air, mostly as thermal energy.
