    • Give an example of a wave that MUST have a medium to travel through. Why must it have a medium?

Activities

    • Slinky waves activity

    • Waves notes, practice, discussion

      • Types of waves

        • Transverse - wave motion and particle motion are perpendicular to each other

        • Longitudinal - wave motion and particle motion are parallel to each other

      • Wave measurements

        • wavelength (lambda) - the length of one wave (before it starts repeating) (meters)

        • Amplitude (A) - the maximum displacement from equilibrium of a wave (meters)

        • Period (T) - the time for one complete wave to go by a single point in space (seconds)

        • frequency (f) - the number of waves that go by a point in space each second (Hz, 1/sec)

        • wavespeed (v) - the rate at which a wave propagates through space (m/sec)

        • f = 1 / T

        • v = (lambda) / T

        • v = (lambda) * f
