Marine Survey...

Question

Marine Survey ship sends a sound wave straight to the seabed it detects an echo 4 seconds later what is the approximate depth of the sea

Open in App

Solution

Lets the velocity(v) of sound wave in sea water is 1400 m/s
Let d be the depth of the sea
Then applying the formula v=2d/t
given that t=4 s
then
1400=2×d/4
d=(1400×4)/2
d=2800m=2.8 km
