11-9 Shock Waves and Sonic Boom

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.

  1. 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

  2. 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. • Pulse-Echo Technique • http://www.layyous.com/ultasound/ultrasound_video.htm

  3. Homework (add to Monday) • P379 60 and 63
