Part a - whale communication.
blue whales apparently communicate with each other using sound of frequency 17.0hz , which can be heard nearly 1000km away in the ocean. what is the wavelength of such a sound in seawater, where the speed of sound is 1521m/s ?
? 1 =
m
part b - dolphin clicks.
one type of sound that dolphins emit is a sharp click of wavelength 1.50cm in the ocean. what is the frequency of such clicks?
f =
khz
part c - dog whistles.
one brand of dog whistles claims a frequency of 26.0khz for its product. what is the wavelength of this sound?
? =
cm
part d - bats.
while bats emit a wide variety of sounds, one type emits pulses of sound having a frequency between 39.0khz and 78.0khz . what is the range of wavelengths of this sound?
? min,? max =
mm
part e - sonograms.
ultrasound is used to view the interior of the body, much as x rays are utilized. for sharp imagery, the wavelength of the sound should be around one-fourth (or less) the size of the objects to be viewed. approximately what frequency of sound is needed to produce a clear image of a tumor that is 1.00mm across if the speed of sound in the tissue is 1550m/s ?
f =
mhz
