Δp = (1.3 Pa) sin π[(3.00 m^-1)x - (300 s^-1)t].

Is the pressure of a wave.

Find frequency

## Homework Equations

## 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.
