Echolocation is a physical processes used by dolphins and other animals to navigate through their surroundings and search for prey. In using echolocation, suppose a dolphin emits a high-frequency ultrasonic wave whose frequency is 2.5 MHz (M = Mega = 1 million = 1x10 6). If the velocity of sound in seawater is 1500 m/s, what is the wavelength of this wave?
| a. |
0.375 mm |
|
| b. |
0.60 mm |
|
| c. |
3.75 m |
|
| d. |
6.0 m |
|
| e. |

Dolphins of the open ocean are classified as Type II Odontocetes (toothed whales). These animals use ultrasonic "clicks" with a frequency of about 55 kHz to navigate and find prey Suppose a dolphin sends out a series of clicks that are reflected back from the bottom of the ocean 90 m below. How much time elapses before the dolphin hears the echoes of the clicks
