sinusoidal sound wave moves through a medium and is described by the displacement wave function s(x, t) = 1.84 cos(15x %u2212 885t)where s is in micrometers, x is in meters, and t is in seconds.
(a) Find the amplitude of this wave.
(b) Find the wavelength of this wave.
(c) Find the speed of this wave.
(d) Determine the instantaneous displacement from equilibrium of the elements of the medium at the position x = 0.0508 m at t = 2.98 ms.
(e) Determine the maximum speed of a element's oscillatory motion.
