Question 226

A research vessel uses sonar to determine the depth of the ocean floor. A pulse of sound is emitted from the bottom of the vessel. The sound travels through the water, reflects off the ocean floor, and is detected by the vessel's receiver again after 1.6 s.

The speed of sound in seawater is 1500 m/s.

How deep is the ocean floor below the bottom of the vessel?

A

600 m600\text{ m}600 m

B

1200 m1200\text{ m}1200 m

C
