A train is moving at 30m/s in still air. The frequency of the locomotive whistle is 500Hz & The speed of the sound is 345m/s. Then which of the following statement is correct: -
  • a)
    The apparent wavelengths of sound in front of locomotive are ”0.60 m".
  • b)
    The apparent wavelength behind the locomotive is respectively 0.75m.
  • c)
    If a wind of speed 10m/s is blowing in the same direction as that in which the locomotive is travelling the apparent wavelength in front of the locomotive will be 0.65m.
  • d)
    In the case of wind flowing the apparent wavelength behind the locomotive is 0.63m.
Correct answer is option 'B,C'. Can you explain this answer?
