Question

As long as the amplitude is large enough, the human ear can respond to longitudinal waves within a frequency range of approximately 20.0 Hz to 20.0 kHz. a) If you had to mark the beginning of each complete wave pattern with a red dot for the long wavelength sound and with a blue dot the short wavelength sound, what distance would there be between the red dots and what Would there be the distance between the blue dots? b) Suppose you repeat part a) in water, where the sound travels at 1480 m / s. How far apart would the points be in each set? Could you easily measure your separation with a tape measure?

a	a) 9 cm b) 6 cm
b	a) 1.72 cm b) 7.4 cm
c	a) 7 cm b) 0 cm
d	a) 4 cm b) 2 cm
