## Homework Statement

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 speakers 4.0 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 and2.3 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.

## Homework Equations

PD = (n-1/2) λ

## The Attempt at a Solution

f = v/(lambda) = 350/6(2n + 1) = 58.33/(2n+1) ... n belongs to integer

Sorry i have no idea what I'm doing nor do i understand the question...

Could someone please direct me to a couple of videos/helpful links that would actually help me understand what's going on here? This is for my online physics course that I'm taking, and it's hard to actually follow along through a webpage.
