  1. PHYSICS and mathOF SOUND

  2. Stationary sound source

  3. DOPPLER EFFECT http://video.google.com/videosearch?q=doppler+effect&hl=en&emb=0&aq=f# Doppler Effect = change in pitch or frequency due to moving sound source or receiver

  4. Super Sonic & Breaking the Sound Barrier Sonic boom is a noise similar to thunder caused by an object moving at supersonic speeds, faster than sound, about 750 mph.

  5. Any elastic material can transmit sound. • Echoes are reflections from smooth, hard surfaces. • Echo free rooms sound “dead.”

  6. Calculating the speed of a wave(remember  speed is distance over time) V = lf Hz m/s m 1/s

  7. V = lf • A wave has a frequency of 4.05 hertz and a wavelength of 4.00m. What is the wave’s speed? f =4.05Hz l = 4.00m V = lf v = (4.00m)(4.05Hz) v = 16.2 m/s

  8. V = lf • = V • f • f= V • l

  9. Noah stands 170 meters away from a steep canyon wall. He shouts and hears the echo of his voice one second later. What is the speed of the wave? Total distance = 170m+170m =340 m Time = 1 s v = d/t v = / v = 340 m/s 340 m 1 s
