9. The apparent change in the frequency of a sound wave as the source and the observer move towards or away from each other is called the As an ambulance approaches you, you hear a (softer / louder / lower-pitched / higher-pitched ) sound because wavelength and frequency As an ambulance passes you and moves away, you hear a (softer / louder / lower-pitched / higher-pitched ) sound because wavelength and frequency 10. From the equation v = Af, wavelength and frequency are (directly / inversely ) proportional and the speed is related to wavelength and frequency because it only depends on the 11. Rank the following media from fastest to slowest speed of sound: cold air, hot air, water, gold, wood.
