Dolphins are extraordinary intelligent animals that has a special feature of echolocation. A yellow submarine lost its location radar and has been at the ocean floor for 4-days at a speed of 250m/s. A dolphin nearby is moving at a speed of 150m/s and has emitted a sound frequency of 14 000Hz. Find the wavelength and its frequency that sound be released by the yellow submarine in order to be located by the dolphin. Speed of the sound in water 1480m/s.
