Homework Help: Physics

Posted by Phil on Saturday, November 29, 2008 at 2:34pm.

This question has me very lost.

Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 11 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 50 cm. What is the wavelength of the sound?

Also

If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum?

I've tried like 5 different ways, none seem to work.

Can someone please how to approach it the correct way.

Thanks in Advance.
