Sound Waves and the Doppler Effect — Homework
Decide whether each problem is about the speed of sound itself or about a frequency shift (Doppler) before setting it up.
- 1.Thunder is heard 2 seconds after a lightning flash. Find the distance to the storm.
- 2.Find the wavelength of a 220 Hz tone in air (v=343 m/s).
- 3.A train horn emits 600 Hz while receding from a listener at 20 m/s (speed of sound 343 m/s). Find the observed frequency.
- 4.Explain the difference between pitch and loudness, and state which wave property each corresponds to.
- 5.Describe a real experience hearing the Doppler effect (a passing car, train, or siren) and explain what you heard using this week's ideas.
