Calculating Depth of Sea | Fathometer Used To Calculate Depth of Sea
The depth of a sea is calculated by equipment named as Fathometer. This device produces ultra sonic sound waves of frequency more than 20,000Htz. These waves propagate in the sea and thus cannot be heard by human beings. This device is fixed to the bottom of a ship. Then it produces the sound waves into the sea in downward direction. These waves reach the bottom of the sea and get reflected back. The time takes for these waves to return back to the device is calculated and the depth of the sea can be calculated accordingly. It can be known by multiplying the speed of the waves with half of the time required for the wave to make a trip.
