(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two adjacent sources each emit frequency 800 hz in air (340 m/s). how far would source 1 have to be moved so an observer in front of the sources would hear no sound? .321 .213 .123 or .312.

2. Relevant equations

f' = f/(1+ vsource/vsnd)

3. The attempt at a solution

i tried to calculate wavelength so that the frequency is below 20 hz (human limit) and figure it out from there but im stuck? please help, thank you
