You are standing at rest in the middle of a highwa. A car is traveling directly toward you at a speed of 30.0 m/s. The car's horn is emitting sound waves with a frequency of 440 Hz. What is the frequency heard by you? The answer is 482 Hz but I am confused on how to get to the answer! Thank you in advance!

Answer #1

f = f'*(vs/vs-vc)

here vs = velocity 0f sound = 340 m/sec

f = 440*(340/340-30) = 482.58 Hz
