Question

A ship hears the echo from a sound wave 4s after it has been emitted. If the speed of sound in water is 1500m/s, calculate the depth of the water beneth the ship.

Answer 1

Answer:

Depth of the sea =$750m$

Explanation:

Given :

Time taken by a ship to hear an echo = $4 seconds$

Speed of sound in water is = $1500m/s$

To find : The depth of the water beneath the ship ?

Step by step answer :

Assume depth of water beneath the ship = 'n'

The sound needs to trip very cheap of the ocean and obtain mirrored back to the ship itself, therefore total distance traveled by the sound is $2n.$

So, $2n = vt$

$2n = 1500 × 4n = 3000m$

So the depth of water beneath the ship is $3000m$

Note :-

Echo - An echo is a sound caused by the reflection of sound waves from a surface back to the perceiver. it's the reflection of sound, incoming at the perceiver it slow when the direct sound.
