Bats produce calls for the echolocation of prey items; to do so, their calls need to bounce off the target and come back to them. sound waves tend to be reflected by objects larger or equal to the wavelength of the sound. for the following questions, use the appropriate values for cthat you find in your class notes.
(a) what minimum frequency (in khz) of calls would a bat need to produce to locate a 0.7inch moth?
(b) what is the period of a wave at this frequency?
(c) what would the wavelengthof this call be (in meters) if the bat were somehow to produce the sound in the water?
(d) what would the period of this waterbornewave be?
