LONGITUDINAL WAVES If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Example: (i) Sound waves are longitudinal waves. Moreover, this is how one can contrast the transverse wave with a longitudinal wave. SONAR (Sound Navigation And Ranging) is a technique for determining water depth and locating underwater objects, such as reefs, submarines, and schools of fish. Waves. Im Untersuchungszeitraum ist zum einen der Übergang von der Sekundarstufe I in die Sekundarstufe II für die ältere Kohorte enthalten. A longitudinal wave in air is represented graphically by plotting density of air against distance from source.

Longitudinal waves are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of propagation of the wave. Therefore, sound wave is called a longitudinal wave.
