What is the Doppler effect? Assume that a sound source is moving toward a sound detector at a speed of 60 m/s. According to the stationary detector, by what fraction does the frequency of the sound shift? Assume the speed of sound to be 330 m/s. Will the frequency appear to be higher or lower? Assume now police operated microwave radar. How fast would a car need to be moving in order to achieve the same frequency shift fraction? Assume the speed of light to be 3 X 10 to 8th m/s.
