1. Is interference a property of some types of waves only or is it a property of all types of waves? 2. When a wave source moves towards a receiver, does the receiver encounter an increase in wave frequency, wave speed or both? 3. Suppose a piano tuner hears 3 beats per second when listening to the combined sound from her tuning fork and the piano note being tuned. After slightly tightening the string, she hears 2 beats per second. Should she loosen the string or should she further tighten the string? Why?
