The Speed of Sound

Sonar (Sound Navigation and Ranging) is a technique that uses sound propagation to detect distances to objects or communicate information. Sonar works by emitting sound waves, which travel through a medium (like air or water) and reflect off objects. By analyzing the reflected sound waves (i.e., the echoes), it's possible to determine the distance, size, shape, and speed of objects in the environment. There are two primary types of sonar.
