1. Homework Statement
Two speakers S1
and S2 derived by the same amplifier and placed at y=1
and y = - 1.The speakers vibrate in phase at 600 Hz. A man stands on the x-axis at a very large distance from the origin and starts moving parallel to the Y - axis. The speed of sound in air is 330ms-1
at what angle will the sound drop to a minimum for the first time?
as minimun occurs at destructive interferenc
Δx = S2Y - S1Y = (2n-1)λ/2
for the first minima Δx = λ/2
but how to calculate Δx in terms of θ ,i an not able to from the geomentry of problem[/B]
