LEARN MORE REMARKS If the train were going away from the observer, v, - -40.0 m/s would have been chosen Instead. QUESTION Does the Doppler shift change due to temperature variations? If so, why? For typical daily variations in temperature in a moderate climate, would any change in the Doppler shift be best characterized as nonexistent, small, or large? Yes. A change in temperature changes the speed of sound and the Doppler shift, but only Insignificantly No. Temperature does not...

One way of measuring the frequency of a sound is to make measurements of the interference pattern that is created when the sound is produced by two sources. You find that for two sources, the sound is loudest when you are equidistant from the sources. You then determine that there is a minimum in intensity when you are 2.3 m farther from one source than the...
