Question

An echo sounder operates by measuring the time required for a ________. radar beam to travel from a harbor patrol boat to a fuzz-buster on a speeding yacht sound pulse travels from a ship to the seafloor and back light beam to travel from a satellite at a known altitude to the sea bottom and back radar beam to travel from a ship to the seafloor and back

Answer 1

Answer:

sound pulse travels from a ship to the seafloor and back

Explanation:

An echo sounder employees techniques used in measuring the depth of the water body. Sound waves are usually passed from the ship into the sea and the time required for the waves to travel from the ship to the sea floor and back is usually recorded.

It is used in the calculation of the speed of sound in water at that point in time which varies according to the depth and physical characteristics of the water body involved.
