Solving for source frequency.

## Inputs:

wave velocity (v)
source velocity (us)
wavelength behind the source (λb)

## Conversions:

wave velocity (v)
= 0
= 0
meter/second
source velocity (us)
= 0
= 0
meter/second
wavelength behind the source (λb)
= 0
= 0
meter

## Solution:

source frequency (f0)
= NOT CALCULATED
