Problem C12: Two speakers, separated by a distance n₁, are producing sinusoidal sound coherently in phase. At the point A in the figure, the sound waves are in phase and experience constructive interference. If one walks from point A to point B in the figure, the sound gradually diminishes in loudness until, at the pointt B, the sound waves experience destructive interference. Point B is a distance n₂ directly in front of one of the speakers. If the wavelength of the sound is n₃, what is n₃? Note that n₁, n₂ and n₃ have the same units of distance.

n1 =	n2 =	Input n3:
