The standard frequency of the musical pitch called “middle C” is 261.6 Hz. How fast, in meters per second, would a source emitting a tone of middle C have to move toward you so that you would hear the pitch C# (C sharp) above middle C, with a frequency of 277.2 Hz? Assume that takes place in air at a high altitude, where the speed of sound is 303 m/s please show work

Question: To demonstrate the Doppler effect, your lecturer puts a tone generator playing a 564 Hz tone in a ball tied to a rope and swings it around. As it swings, you hear a maximum frequency of 578 Hz from your seat in the middle of the large lecture hall. Assume the speed of sound through the air is 336 m/s. Part 1) What speed is the ball moving at? v = 8.14 m/s Your last answer was interpreted as...

Middle C has a speed of 1500 m/s in water and 340 m/s in air. Does it have a longer or shorter wavelength in water than in air and why? 1. Shorter; the speed of sound is greater in water than in air. 2. Shorter; water is denser than air. 3. Longer; the speed of sound is greater in water than in air. 4. Longer: water is denser than air.
