The equation of a sound wave in air is given by p = (0-01 N m2) sin[ (1000 s) t-(3-0 m )x] (a) Find the frequency, wavelength and the speed of sound wave in air. (b) If the equilibrium pressure of air is 10x105N m2, what are the maximum and minimum pressures at a point as the wave passes through that point.
