Question

3. A musician in a car travelling at a speed of 28.0 m/s plays a trumpet (modeled as an open-closed tube 28.0 cm long). The note played is at its fundamental frequency. What frequency does an observer standing on the side of the road hear as the car approaches her? Assume the speed of sound is 340 m/s.

Step 1

Given: Length of the open-closed tube (L) = 28.0 cm = 0.28 m Speed of sound (v) = 340 m/s The fundamental frequency of an open-closed tube is given by: f = v / (2L) Substitute the given values: f = 340 m/s / (2 * 0.28 m) f = 607.14 Hz Show more…
