Question

We will assume that a sound wave, once generated and emitted, will propagate uniformly in all directions
of 3-dimensional space. Find an expression for the displacement s(r, t) of the air particles from equilibrium,
where r is the radial distance from the source, and t is time.
Introduce physical constants/coefficients, with appropriate physical dimensions, when necessary.

A string of 1 m length clamped at both ends is plucked in the middle to generate a standing wave. Take the frequency of the first harmonic to be 10 Hz and the amplitude of the oscillations to be 2 cm. Consider the motion to be a simple harmonic one where appropriate. Calculate the speed of the progressive waves that result in the standing wave. Provide your answer in m/s.
Use dimensional analysis to find how the speed vvv of a wave on a string of circular cross section depends on the tension in the string, T, the radius of the string, R, and its mass per volume, ρ (rho). Express your answer in terms of the variables T, R, and ρ(rho).
