1. The problem statement, all variables and given/known data
A loudspeaker at the origin emits sound waves on a day when the speed of sound is 340 m/s. A crest of the wave simultaneously passes listeners at the coordinates (38m,0m) and (0m,29m). What are the lowest two possible frequencies of the sound?
2. Relevant equations
D(x,t)=Asin(kx-wt+\phi)
D(y,t)=Asin(kx-wt+\phi)
3. The attempt at a solution
I do not know where to start with this problem. I recieved some advice from the TA, but I am still confused.
