Provided the amplitude is sufficiently great, the human ear can respond to longitudinal waves over a range of frequencies from about 20.0 hz to about 20.0 khz.
a)if you were to mark the beginning of each complete wave pattern with a red dot for the long-wavelength sound, how far apart would the red dots be?
b)if you were to mark the beginning of each complete wave pattern with a blue dot for the short-wavelength sound, how far apart would the blue dots be?
c)in reality would adjacent red dots be far enough apart for you to easily measure their separation with a meterstick?
d)in reality would adjacent blue dots be far enough apart for you to easily measure their separation with a meterstick?
e)suppose you repeated part a in water, where sound travels at 1480 {\rm{ m/s}}. how far apart would the red dots be ?
f)suppose you repeated part a in water, where sound travels at 1480 {\rm{ m/s}}. how far apart would the blue dots be ?
g)could you readily measure their separation with a meterstick?
