Problem: Two identical loudspeakers, speaker 1 and speaker 2, are 2.0 apart and are emitting 1700- sound waves into a room where the speed of sound is 340 . Is the point 4.0 in front of speaker 1, perpendicular to the plane of the speakers, a point of maximum constructive interference, a point of perfect destructive interference, or something in between?

FREE Expert Solution

Constructive interference:

x=mλ

Destructive interference:

x=(m + 12)λ

Speed, frequeny and wavelength relationship:

v=fλ

From Pythagoras theorem:

s2 = (22 + 42)(1/2) = 4.472
