11-9 Shock Waves and Sonic Boom

Supersonic means traveling faster than the speed of sound…the speed is given as a Mach number

… x sos/sos.

A shock wave is a very large wave built by constructive interference.

The bow-wave of a boat would be an analogy for the shock wave caused by a jet.

The angle of the apex of the shock-wave can be found by the equation … q=vsound /vobject


12 10 applications of sound

12-10 Applications of Sound

  • Sonar…SOundNavigation And Ranging

  • Ultrasound… sos in body 1,500 m/s …smallest wavelengths are about 1.5 mm…the smaller the wavelengths of sound used in ultrasound or sonar, the smaller the objects that can be detected.
