(Echolocation by a Porpoise) Problem 6. Returning tchelecatien Beanfore A porpoise sends an echolocation pulse as it tracks the location of a diver. The pulse is emitted in all directions. The power of the pulse is 3 x 10-2 w. The intensity of the pulse at the position of the diver is 1.5 x 10-5 W/m^2. Outgelng Echolocation Bantern What is the distance between the diver and the porpoise? Express your answer in m. A. B. The frequency of the pulse is 60 kHz. What is the wavelength of the pulse given the speed of sound in seawater is 1540 m/s? Express your answer in cm.
