Answer: Option C
Answer: (c)
Echo sounding is the technique of using sound pulses to find the depth of water. The interval from the emission of a pulse to the reception of its echo is recorded, and the depth calculated from the known speed of propagation of sound through water.
This information is then typically used for navigation purposes or in order to obtain depths for charting purposes.
