1) sonar waves are used for underwater surceillance and measurements (depth) 2)visualising images in utero-ULTRASONOGRAPHY. 3)sonar is used for treatment in physiotherapy
basically same but sonar uses ultta sonic waves and echo uses sound in air
Sonar navigation uses sound waves; radar navigation uses electromagnetic waves (usually radio eaves).
sonar
As the name suggests, sonar uses sonic waves (sound). Typically, sonars use sounds with frequencies inaudible to human ear.Another answer:Actually, sonar uses a wide range of frequencies. Very low frequencies (100 Hz to 1 kHz) are used for long range detection and deep sea floor sounding. Midrange frequences (1 kHz to 10 kHz) are used for target identification. Ultrasonic frequencies (50 kHz and up) are used in navigation and commercial sonar devices like fish finders.
Bat uses sonar. Humans don't.

A submarine uses sonar, like a bat uses echolocation to see.
A sonar uses one device and a sea beam uses a dozen sonar devices.

Sonar navigation uses sound waves; radar navigation uses electromagnetic waves (usually radio eaves).
Sonar uses electricity, so the source of energy is either a generator or a battery.
sonar uses the theory of plate tectonics because it makes sound waves and the sound waves con hear them
A bat uses "sonar" because of it's lack of sight. A bat's "sonar" is the closest thing it has to sight, as it can identify individual objects with it.
