A car travelling at constant speed passes by a stationary pedestrian as the car driver sounds the horn. As the car approaches the pedestrian she hears the horn sounding at 50 Hz. Once the car has driven past her, she hears the horn sounding at 10 Hz. Calculate the frequency in Hz of the sound waves emitted by the car horn.
