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.

Current Attempt in Progress Earthquakes generate sound waves inside Earth. Unlike a gas, Earth can experience both transverse (S) and longitudinal (P) sound waves. Typically, the speed of S waves is about 4.03 km/s, and that of P waves 8.20 km/s. A seismograph records P and S waves from an earthquake. The first P waves arrive 3.23 min before the first S waves. If the waves travel in a straight line, how far away does the earthquake occur? Number i Units

A fisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. It takes 2.90 s for the boat to travel from its highest point to its lowest, a total distance of 0.620 m. The fisherman sees that the wave crests are spaced 7.80 m apart. Part A How fast are the waves traveling? v = 1.34 m/s Submit Part B Previous Answers Correct Correct answer is shown. Your answer 1.345 m/s was either rounded differently or used a different number of significant figures than required for this part. Important: If you use this answer in later parts, use the full unrounded value in your calculations. What is the amplitude of each wave?
