A. whale communication. blue whales apparently communicate with each other using sound of frequency 17.0 hz, which can be heard nearly 1000 km away in the ocean. what is the wavelength of such a sound in seawater, where the speed of sound is 1531 m/s? b. dolphin clicks. one type of sound that dolphins emit is a sharp click of wavelength 1.50 cm in the ocean. what is the frequency of such clicks? c. dog whistles. one brand of dog whistles claims a frequency of 25.0 hz for its product. what is the wavelength of this sound? d. bats. while bats emit a wide variety of sounds, one type emits pulses of sound having a frequency between 39.0 hz and 78.0 hz. what is the range of wavelengths of this sound? 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 1.00 mm across if the speed of sound in the tissue is 1550 m/s?
