Homework Statement
A pair of speakers connected to the same signal generator face each other, one at x=0 and the other at x=1.5m. If they are producing a sound frequency of 2000Hz what are the points (position x) of constructive interference between the speakers? Express your answer in terms of λ
Homework Equations
r2-r1=nλ
The Attempt at a Solution
I calculated the wavelength from v=fλ
λ=343m/s / 2000Hz
λ=0.1715m
then from r=L-nλ/2
n=0 r=1.5/2=0.75m
n=1 r=1.5-.1715/2=0.66m
n=2 r=1.5-2(0.1715)/2= 0.58m
