When poked by a spear, an operatic soprano lets out a 1169 Hz shriek. What is its wavelength (in m) if the speed of sound is 345 m/s?
At a rock concert, the sound intensity 1.0 m in front of the bank of loudspeakers is 0.10 W/m2. A fan is 30 m from the loudspeakers. Her eardrums have a diameter of 8.4 mm. How much sound energy is transferred to each eardrum in 1.0 second?
Alysson joins a race. She is running at a constant pace of 2m/s. Eve, another runner who
enjoys running in races, is behind her with a megaphone encouraging other runners. If
Eve runs at a pace of 3m/s, and her voice has an average frequency of 800HZ, what is the
apparent wavelength of sound that Alysson hears? Let vsound= 340 m/s.
