What frequence is detected by a stationary train

Reference no: EM13544065

If the detector moves toward the source, vd is positive; if the source moves toward the detector, vs is positive. A train moving away from a detector at 25 m/s blows a 348 Hz horn. What frequence is detected by a stationary train? The velocity of sound in air is 343 m/s.
