While driving at a constant speed of 75 km/h, you are passed by a car traveling at 121 km/h. If the frequency of light emitted by the taillights of the car that passes you is 4.3 multiplied by 1014 Hz, what frequency will you observe? (Express this value to 9 significant digits.)
What is the change in frequency?
