The sonar signals are audio wave signals created by the transmitter that can pass through water. When Radio signals are created in air it is called radar. Usually sonar are used in underwater applications, and navy defense.
Sonar waves are created by emitting sound pulses into the water from a transducer. These sound pulses travel through the water until they hit an object, which reflects the sound back towards the source. By measuring the time it takes for the sound to return, sonar systems can calculate the distance and shape of the object.
