Speakers A and B are emitting sound wave in phase with the same wavelength 175 Hz. Speaker A is a distance 2.00 m to the left of speaker B and point P is 3.50 m to the right of B, so 5.50 m to the right of speaker A. The speed of sound in the air is 350 m/s. Is the interference at point P constructive or destructive?

Question

Speakers A and B are emitting sound wave in phase

with the same wavelength 175 Hz. Speaker A is a distance 2.00

m to the left of speaker B and point P is 3.50 m to the right of B,

so 5.50 m to the right of speaker A. The speed of sound in the

air is 350 m/s. Is the interference at point P constructive or

destructive?
