1. The problem statement, all variables and given/known data Δp = (1.3 Pa) sin π[(3.00 m^-1)x - (300 s^-1)t]. Is the pressure of a wave. Find frequency 2. Relevant equations 3. The attempt at a solution Angular frequency = 300s^-1 = 300 hertz. Frequency = angular frequency / 2pi = 47.746 Someone, please explain how I managed to screw up that very simple equation.
