Two stereo speakers mounted 4.52 m apart on a wall emit identical sound waves. You are standing at the opposite wall of the room at a point directly among the two speakers. You walk 2.11 m parallel to the wall to a location where you first notice that the sound intensity is much less. If the wall along which you are walking is 13.3 m from the wall with the speakers, what is the wavelength of the sound waves? (Answer: 1.4 m) can someone describe the process and formulas?
