celebrity holds a press conference, which is televised live. A television viewer hears the sound picked up by a microphone directly in front of the celebrity. This viewer is seated 1.8 m from the television set. A reporter at the press conference is located 4.5 m from the microphone and hears the words directly at the very same instant that the television viewer hears them. Using a value of 343 m/s for the speed of sound, determine the maximum distance between the television viewer and the celebrity

Two small speakers, 0.680 m apart, are facing in the same direction. They are driven by one 666 Hz oscillator and therefore emit identical sound waves in phase with one another at the respective points of origin. (The speed of sound waves in air is 343 m/s.) Two speakers are side by side, with one speaker on the left and one on the right. The speakers are separated by a distance d and emit sound waves in the same direction. A man stands directly in front of the speaker on the right but a distance x away from the right speaker. (a) A listener wishes to stand in front of one of the speakers, at the closest point (i.e., smallest x-value) where intensity is at a relative maximum. At what distance x from the nearest speaker should she position herself? (Enter your answer in m.)  m (b) The listener now wishes to stand at the closest point along that line where intensity is at a relative minimum. At what distance x should she position herself now? (Enter your answer in m.)  m

A celebrity holds a press conference, which is televised live. A television viewer hears the sound picked up by a microphone directly in front of the celebrity. This viewer is seated 1.9 m from the television set. A reporter at the press conference is located 4.3 m from the microphone and hears the words directly at the very same instant that the television viewer hears them. Using a value of 343 m/s for the speed of sound, determine the maximum distance between the television viewer and the celebrity.

Your answer is partially correct. A man strikes one end of a thin rod with a hammer. The speed of sound in the rod is 15 times the speed of sound in air. A woman, at the other end with her ear close to the rod, hears the sound of the blow twice with a 0.16 s interval between; one sound comes through the rod and the other comes through the air alongside the rod. If the speed of sound in air is 346 m/s, what is the length of the rod?
