  1. Music • Music is defined as sound waves that are used in a regular pattern.

  2. Music • Musical Instruments vibrate & resonate to create the pitch we hear. • Each instrument also creates a distinctive wave form to identify it. [http://amath.colorado.edu/pub/matlab/music/F_InstrumentWaves.gif]

  3. Music • String instruments have strings or wires that create standing waves to make sound. [http://ffden-2.phys.uaf.edu/211.fall2000.web.projects/Peter%20Alden/waves2.jpg]

  4. Music • Wind Instruments use a vibrating column of air. [http://www.ibiblio.org/obp/electricCircuits/AC/02377.png]

  5. Uses of Sound Waves • Acoustics is the study of sound waves. • Acoustic engineers look to minimize reverberation, or echoes in buildings [http://www.acoustics.salford.ac.uk/images/common/anechoic_tristan.jpg]

  6. Uses of Sound Waves • Echolocation is sending out sound waves and locating objects based on their reflections. [http://evolution.berkeley.edu/evosite/evo101/images/bat_echolocation_225.gif]

  7. Uses of Sound Waves • SONAR • Sound Navigation and Ranging • Finding objects underwater with sound waves. [http://www.divediscover.whoi.edu/images/sonar_multibeam_top.gif]

  8. Uses of Sound Waves • Ultrasound consists of sound waves above the human hearing level. • Can be used in medicine to “see” inside patients bodies.
