Question

A ship sends a high frequency signal and receives an echo after 4 second what is the depth of the sea at speed of sound in water is 1500 meter per second

Answer 1

Answer:

d=Vt/2

d=1500*4/2

=3000metres or 3km

Answer 2

Explanation:

It is given that,

Speed of sound in water, v = 1500 m/s

Echo is received after 4 second

Let d is the the depth of the sea. The distance covered by the sound is 2d. The speed of any wave is given by :

$v=\dfrac{2d}{t}$

$d=\dfrac{vt}{2}$

$d=\dfrac{1500\times 4}{2}$

d = 3000 meters

So, the depth of the sea is 3000 meters. Hence, this is the required solution.
