1. How would the observed frequency compare to the emitted frequency if the observer was moving in the same direction at the same velocity as the car? Draw a diagram to support your answer. 2. Based on your findings, how would the observed frequency compare to the emitted frequency if the observe was moving toward a stationary car? Draw a diagram to support your answer. 3. How would the observed frequency compare to the emitted frequency if the observer was moving away from a stationary car? Draw a diagram to support your answer.
