Two identical loudspeakers are located at points A & B, 2 m apart. The loudspeakers are driven by the same amplifier (coherent and are in phase). A small detector is moved out from point B along a line perpendicular to the line connecting A & B. Taking speed of sound in air as 332 m/s, find the frequency below which there will be no position along the line BC at which destructive interference occurs.

(83 Hz)
if path difference at detector is always less than λ/2 then no destructive interference is possible. Here max. path difference is 2
> 2
λ > 4 m
> 4 m
n < 
< 
< 83 Hz
