WebJun 13, 2024 · Assuming the speed of sound v = 343 m/s (the 20 C dry-air value), fd = 295* (343+0)/ (343+33) = 269.11 Hz. Sloppily stated question. The train moves away in which direction, the same "away from the detector" direction as the emitting train? Which train is the 1st one, the stationary one or the 33 m/s one? WebIf the source and the observer are moving with the same speed in the same direction, vo and vs will be equal in magnitude but with the opposite sign; the frequency of the sound will therefore remain unchanged, like the sound of a train whistle as heard by a passenger on the moving train.
