1 P ROPERTIES AND D ETECTION OF S OUND Waves 2011-2012

2 S OUND Sound is caused by the vibration of a medium. Your voice results from a vibration of your vocal chords. The sound of a violin is produced by the vibration of strings. Sound cannot propagate through a vacuum!

3 W HAT K IND OF W AVE IS S OUND Sound is a mechanical wave – It results from particle- to-particle interaction. Sound is a longitudinal wave – The particles move along the direction of the wave. Sound is a pressure wave – It has regions of compression and rarefaction.

4 S OUND W AVE D EFINITIONS Pitch – our subjective impression of the frequency of sound Infrasonic – sound waves with frequencies below 20 Hz Ultrasonic – sound waves with frequencies above 20,000 Hz Compression – region of high pressure Rarefaction – region of low pressure

5 T HE D OPPLER E FFECT The apparent change in frequency due to the motion of the source (or receiver). The greater the speed of the source (or receiver), the greater the Doppler effect.

Like all waves, sound waves are produced by a vibration.  A tuning fork vibrates to produce a sound.  A guitar string vibrates to produce a sound.

When something moves back and forth, up and down, or side to side we say it vibrates. A vibration is a wiggle. When this wiggle moves through space and.
