Bell Activity: How are waves and energy related?

• • How energy and waves are related

  • Anatomy of a wave

    • Node - the part of a wave at equilibrium

    • Antinode - the part of a wave furthest from equilibrium

      • • Crest - high point of a wave

        • Trough - low point of a wave

    • Wavelength - the distance between two identical parts of a wave

    • Frequency - the number of waves that go by a point each second

    • Period - the time for one complete cycle of a wave to go by

    • Amplitude - the distance from equilibrium to the antinode of a wave

  • Wave speed

    • wave speed = frequency times wavelength

    • example problems

  • Page 519: practice problems 1-3 due Thursday

  • Wave speed activity

  • Calculating the speed of waves on a spring. Due Friday.
