Additional Details

Conceptual Physics Alive: Vibrations & Sound 1 includes a digital video and questions set with answers.

Observe Paul Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. In this video, a coiled toy is used to illustrate the difference between transverse and longitudinal waves. Interference of waves and beats of sound is also demonstrated, followed by an explanation of shock waves and sonic booms. Segment length: 32 minutes

Vibrations & Sound 1 Includes:

  • Wiggles and jiggles.
  • Vibrating chalk at the chalkboard illustrates low and high frequencies of vibration. Waves are illustrated when Hewitt walks across the floor to trace out a sine curve.
  • Amplitude and wavelength of a wave.
  • Derivation of wave speed.
  • All electromagnetic waves have the same speed, c = 300000 km/s.
  • Radio-wave wavelengths are calculated for different frequencies.
  • Demonstration of slinky vibration to show longitudinal waves; then transverse waves.
  • Ted Brattstrom demonstrates wave characteristics on an oscilloscope.
  • Wave interference is illustrated on the chalkboard.
  • Hewitt pretends to demonstrate interference by striking a pair of tuning forks out of phase so that the sound from one is canceled by the sound from the other.
  • Beats are defined.
  • Demonstration on the oscilloscope of beats from a pair of tuning forks of slightly different frequencies.
  • Laser discs (CDs).
  • Technological changes discussed, and Hewitt leaves with the question, "What will replace windshield wipers?"
