Noise-canceling headphones are an application of destructive interference. Each side of the headphones uses a microphone to pick up noise, delays it slightly, then rebroadcasts the noise next to your ear where it can interfere with the incoming sound wave of the noise. Suppose you are sitting 1.8 m from an annoying, 310 Hz sound. Part A What is the minimum headphone delay, in ms, that will tend to cancel this noise? Assume one-dimensional motion for the wave along an axis into your ear.

Two loudspeakers emit identical sound waves along the x-axis. The sound at a point on the axis has maximum intensity when the speakers are 22 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 33 cm. Part A What is the wavelength of the sound? Part B If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum?
