Two out-of-phase loudspeakers separated by a distance d emit 170 Hz sound waves along the X-axis. As you walk along the axis, away from the speakers, you hear only maximum intensity pitch. Assuming a sound speed of 340 m/s, what are the two first values for d for such occurrence?

λ=Vf=340170=2

L1-L2=(n+12)λ,   (n=0,1,2,3,...)

P1=(0+12)2=1m

P2=(1+12)2=3m

P3=(2+12)2=5m
