Two audio speakers are placed on a vertical rail. Speaker A is placed at head-level while Speaker B is place at some variable height, \Delta yΔy, above Speaker A. Both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.362 meters. Calculate the lowest height that Speaker B can be placed above Speaker A to produce a minimum of sound heard by person standing \Delta x = 6.73Δx=6.73 meters directly in front of Speaker A.
