The displacement of the air molecules in a sound wave is modeled with the wave function s(x, t) 7.00 nm cos(80.00 m-1x-2.74 x 104 s-t)
(a) What is the wave speed (in m/s) of the sound wave? m/s
(b) What is the maximum speed (in m/s) of the air molecules as they oscillate in simple harmonic motion? m/s
(c) What is the magnitude of the maximum acceleration (in m/s2) of the air molecules as they oscillate in simple harmonic motion? m/s2
