Compute the all parts of given problem:
Problem: A railroad train is traveling at 29.0 m/s in still air. The frequency of the note emitted by the locomotive whistle is 490 Hz. (Assume the speed of sound in air is 344 m/s.)
Part I: What is the wavelength of the sound waves in front of the locomotive?
m
Part II: What is the wavelength of the sound waves behind the locomotive?
m
Part III: What is the frequency of the sound heard by a stationary listener in front of the locomotive?
Hz
Part IV: What is the frequency of the sound heard by a stationary listener behind the locomotive?
Hz
