Bell Ringer: How are waves and energy 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 x wavelength

      • wave speed = distance / time

      • example problems

  • Begin wave speed lab (finish Monday, due Tuesday)
