Problem 2: A periodic vibration at x 0, t 0 displaces air molecules along the x direction by sSmax = 3.9E-05 m. The motion produces a sound wave that travels at a velocity of v 335 m/s with a frequency of f 185 Hz. Take the density of air as pa = 1.20 kg/m3. Smax x = 0 Part (a) Calculate the wavelength A of the sound wave, in meters. Numeric : A numeric value is expected and not an expression. Part (b) Calculate the wavenumber k of the sound, in radians per meter. Numeric : Anumeric value is expected and not an expression. k = Part (c) Calculate the angular frequency of the sound w, in radians per second. Numeric : A numeric value is expected and not an expression. W = Part (d) Calculate the displacement of the air molecules using an function for the traveling sound wave in terms of time and position at time t 0.001 s and displacement x 1.0 m. Numeric : A numeric value is expected and not an expression. s(1,0.001) = Part (e) Write an expression for the maximum pressure exerted by the sound wave APmax in terms of the air density Pa the sound velocity v, the angular frequency w, and the maximum displacement Smax- Expression : APmax =
