  1. Waves

    Slide 1 - Waves

    • And their characteristics
    • CSO: SC.O.PS.2.19 differentiate between transverse and longitudinal waves and model examples of each type and relate to water, light and sound waves.
  2. What is a wave?

    Slide 2 - What is a wave?

    • a disturbance that transmits energy through matter or space.
  3. Two kinds of Mechanical Waves:

    Slide 3 - Two kinds of Mechanical Waves:

    • 1) Longitudinal –
    • the medium moves back and forth in the same direction the waves travels
    • Compression
    • areas where the medium is forced together by the wave
    • Rarefaction
    • the expand area the wave leaves behind
  4. Mechanical Waves Continued

    Slide 4 - Mechanical Waves Continued

    • 2) Transverse
    • the wave moves at right angles to the medium it is traveling through Example: ocean waves
  5. 3 Properties of Waves

    Slide 5 - 3 Properties of Waves

    • 1) Amplitude
    • the maximum distance molecules of the medium are displaced from their original position
    • 2)Wavelength
    • the distance between two consecutive crest or two consecutive troughs
  6. 3 Properties of Waves (cont.)

    Slide 6 - 3 Properties of Waves (cont.)

    • 3) Frequency
    • the number of vibrations that occur in one second of time.
    • measured in hertz 1 Hz = 1 vibration per second
  7. Introduction to Waves: Amplitude, Period, and Frequency

    Slide 7 - Introduction to Waves: Amplitude, Period, and Frequency

  8. MATH!

    Slide 8 - MATH!

    • Wave speed-
    • the velocity at which a wave passes through a medium
    • Velocity (v) = wavelength (__) x frequency (f)
    • v = ___ x f
