1. The problem statement, all variables and given/known data A student enters Best Buy prepared to buy a pair of speakers. Before he does so, he conducts an experiment with them. He places the speakers4.0 m apart and connects a signal generator to both speakers that produces a single and consistent tone. (constant wavelength and frequency) He then walks to a point that is 2.0 m from one speaker and 2.3 m from the other. At that point he notices a quiet “spot”. If the speed of the sound in the room is known to be 350 m/s, calculate the possible frequencies being played by the speakers. 2. Relevant equations PD = (n-1/2) λ 3. The attempt at a solution f = v/(lambda) = 350/6(2n + 1). Am i on the right track? I don't really understand how the 2m and 2.3 m is involved in this question.
