Doppler Effect Frequency Change
Two cars equipped with identical 600 Hz horns drive toward each other, each at 25 m/s. A stationary observer stands between them. If the speed of sound is 340 m/s, how would the observed frequency change if both cars were instead moving away from the observer at 25 m/s?
A
