Sound waves can propagate through the air, water, Earth, wood, metal rods, stretched strings, and any other physical substance. The purpose of this tutorial is to give formulas for calculating the speed of sound. Separate formulas are derived for a gas, liquid, and solid. General Formula ...
A systematic, experimental and numerical search for subharmonic generation and/or amplification was conducted at intermediate times and moderate Reynolds numbers in nonlinear second sound near the superfluid transition. We found that the nonlinear acoustic waves are dynamically monotonic in the sense that ...
