## Homework Statement

A sinusoidal sound wave is described by the displacement wave function

Code:

`s(x,t)=(2.00 μm)cos[(15.7 m^(-1) )x-(858 s^(-1) )t]`

## Homework Equations

## The Attempt at a Solution

Code:

`s (x,t)=(2.00 μm) cos[(15.7 m^(-1) )(0.050m)-(858 s^(-1) )(.003 s) ]`

Why is this this not correct?
