Question

In a SONAR ultrasonic waves are sent into the seawater and the reflected waves from a sunken ship are received after 2s. If the velocity of waves in seawater is 1450m/s. Find the depth of the sunken ship.

Answer 1

Answer:

1450m

Explanation:

Given,

time taken by the waves to return = 2 second

means that it took the wave 1 second to reach the ship and 1 second to come back

so,

speed = distance / time

1450 = distance / 1

1450*1 = distance

distance = 1450 m.
