Question: Explain the working and application of a sonar?
Sonar, short for Sound Navigation and Ranging, is an instrument used to measure the distance and other properties of objects underwater. It works by emitting sound pulses and then listening for the echoes them make when they bounce off of objects in the water. By analyzing the properties of the echoes, such as their intensity and the time it takes them to return, it is possible to detect the location, size, shape, and speed of objects that are underwater.
Sonar is most commonly used in the military, to identify and track submarines, ships, and other objects in the open sea. It is also used in oceanography, for mapping the ocean floor and for tracking the movements of marine animals. In some industries, such as fishing, sonar is used to help locate schools of fish and identify prime fishing spots. Sonar can also be used to explore sunken ships, caves and other areas. In other industries, such as engineering, sonar is used to inspect the structural integrity of bridges, dams, and other infrastructure.
