When sound waves strike the eardrum this membrane ibrates with the same trequency as the sound The highest pitch that typical humans can hear has a pno ofp the ibratng eardrum for this sound? what ae the teuency and anguiar euey Please enter your answers in the order frequency, angular frequency separated with comma 112 , tad/s Part CExplanation / Answer
(A) t = 1/ f = 2.15 x 10^-3 sec
w = 2 pi f = 2928 rad/s
(B) f = 1/T = 1 / (50 x 10^-6) =20,000 Hz
w = 2 pi f = 125664 rad/s
(C)
T_min = 2pi / (4.7 x 10^15) = 1.34 x 10^-15 s
T_max = 2 pi /(2.7 x 10^15) = 2.33 x 10^-15 s
(D) f = 1/T
fmin = 1/T_max = 4.30 x 10^14 hz
f_max = 7.46 x 10^14 Hz
(E) f = 5.70 x 10^6 Hz
T = 1/f = 1.75 x 10^-7 sec
w = 2 pi f = 3.58 x 10^7 rad/s
