Dolphins rely on echolocation to be able to survive in the ocean. In a 20°C ocean, a dolphin produces an ultrasonic sound with a frequency of 105 kHz. Use 1530 m/s for the speed of sound in 20°C ocean water. What is the wavelength à of this sound, in meters? = While remaining stationary, the dolphin emits a sound pulse and receives an echo after 0.180 s. How far away, in meters, is the reflecting object from the dolphin? distance:
