The speed of sound in water is 1498 m/s. a sonar signal is sent straight down from a ship at a point just below the water surfac e, and 1.80 s later the reflected signal is detected. how deep is the ocean beneath the ship?
1 answer:
The 1.8 s is the time for the signal to reach the ocean floor and return to the ship so the time to reach ocean floor = 1.8 / 2 = 0.90 seconds.
