Conceptual Physics Alive: Vibrations & Sound, Radioactivity and Fission & Fusion
Master teacher Paul Hewitt teaches Conceptual Physics. Observe Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. DVD Includes 4 Episodes: Episode 1: Vibrations and Sound I: A coiled toy is used to illustrate the difference between transverse and longitudinal waves. Interference of waves and beats of sound are also demonstrated, followed by an explanation of shock waves and sonic booms. Segment length: 32 minutes Episode 2: Vibrations and Sound II: The reflection, refraction, and speed of sound waves are explained. 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 Episode 3: Radioactivity: The differences between alpha, beta, and gamma radiation are discussed, with emphasis on balancing nuclear equations. Radioactive half-life and techniques for radioactive dating are also explained. Segment length: 40 minutes Episode 4: Fiss
