1. We can describe sound as either a pressure wave or as a displacement wave. Which do you think is a better description?
2. Physically, why is the Doppler shift different for a moving source compared to a moving observer?
3. Why is sound in air a longitudinal wave and not a transverse wave? Answer this question in complete sentences using your own words.
Homework Answers
1) As a pressure wave.
Sound is a Pressure Wave. Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. This is what characterizes sound waves in air as longitudinal waves.

When the source of a wave and an observer move either towards or away from each other the observed frequency of the wave will be different from the frequency at which the wave is emitted. For example, if you are standing by the side of the road and a police car with a siren passes by, the frequency of the sound you hear will be higher when the car is moving towards you and lower when it is moving away...
