Echoes
In maritime context, echoes refer to the sound waves that bounce back from an object after hitting it. Echoes are used in sonar technology to detect the presence and location of underwater objects such as submarines, rocks, and shoals. The time taken for the echo to return to the sonar device is used to calculate the distance of the object from the device. The strength of the echo is used to determine the size and shape of the object. Echoes are an important tool for navigation and safety at sea, as they allow ships to avoid underwater hazards and navigate in low visibility conditions.
