Conceptual Physics Alive: Vibrations & Sound 2 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, Paul Hewitt explains reflection, refraction, and speed of sound waves. A discussion of forced vibrations and resonance culminates with exciting historical footage of the collapse of the Tacoma Narrows Bridge in 1940. Segment length: 43 minutes

Vibrations & Sounds 2 Includes:

  • Hewitt begins with a chalkboard discussion of the waves generated by a bug that bobs up and down on a smooth surface of water.
  • Doppler effect.
  • Bow wave.
  • Shock wave and sonic boom.
  • Mach numbers and the speed of sound.
  • Bullets, shock waves, and mini sonic booms.
  • Crack of a circus whip; a mini sonic boom.
  • Speeds of sound in air, water, and steel compared.
  • Ultrasound and its application for medical use.
  • Dolphins and ultrasound.
  • The molecule-to-molecule conduction of sound.
  • Sound propagation, density, and elasticity.
  • Sound refraction.
  • Interference of sound and its application to tomorrow's jackhammers.
  • Demonstration of tuning forks.
  • Demonstration of a music box piece that sounds louder when pressed against a sounding board.
  • Forced vibration.
  • Resonance.
  • Examples of resonance; kid on a swing in Golden Gate Park, loose front end of Hewitt's car, radios on glass shelves, hotel balcony collapse, bridge collapse.
  • Hewitt's story (with lies!) of the devastating effect a cat would have on the George Washington Bridge in New York.
  • Footage of the famous 1940 Tacoma Bridge collapse ends the lecture. Hewitt continues spoofing about a cat causing the collapse, then directs his class to look in his textbook for a better explanation [of wind-generated resonance].
