Here's the problem:(adsbygoogle = window.adsbygoogle || []).push({});

Two speaks side by side are separated by 1 meter. If the sound intensity is found to reach its first maximum when someone stands 1.0 meter directly in front of one of the speakers ( ie. perpendicular to the line between the speakers) what is the wavelength of the sound wave?

I know that wavelength is velocity over frequency but I don't think that applies here. If I draw a right triangle I can get the hypotenuse which is the distance between the person and the other speaker which is the square root of 2. Then take the difference 1.41 minus 1 = .41 meters. Is this the wavelength?

I'm not sure of my methodology!!!! Help!!!!
