The air pressure variations in a sound wave cause the eardrum to vibrate?
(a) For a given vibration amplitude, are the maximum velocity and acceleration of the eardrum greatest for high-frequency sounds or low frequency sounds?
(b) Find the maximum velocity and acceleration of the eardrum for vibrations of amplitude 1.0 × 10−8 m at a frequency of 20.0 Hz?
(c) Repeat (b) for the same amplitude but a frequency of 20.0 kHz?
