A pressure wave traveling through air is described by the following function p(x, t) in terms of position x and time t. p(x,t) = (1.0 atm) sin[(7.0 rad/m) x - (4.0 rad/s) t] 4 5 What is the pressure amplitude Pmax of the wave? What is the wave number of the wave? What is the frequency f of the wave? f What is the speed up of the wave? Pmax = 1.0 01 7.0 m Incorrect 4.0 Incorrect atm Hz. 0.57 Up= m/s
