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.
The function y(x, t) = A cos(kx - wt) describes a traveling wave on a taut string with the x-axis parallel to the string. If the wavelength of the wave λ = 0.8 m and w = 17.1л/s, what is the speed of the traveling wave? Express your answer in m/s, to at least one digit after the decimal point.

Find the pressure amplitude (in Pa) of a 1.40 kHz sound wave in air, given that the displacement amplitude is 2.30 x 10-8 m. [Note: The equilibrium density of air is p pressure, 1.013 × 105 Pa.] 8.32 Use the relationship between s max and ΔΡ 1.20 kg/m³ and the speed of sound in air is v = 343 m/s. Pressure variations AP are measured relative to atmospheric max' You will need to convert frequency to angular frequency. Don't forget to convert units as needed. Pa
