    Note
    Two types of waves:
    • Longitudinal waves
    • Transverse waves

    Sound waves are longitudinal waves.

    Transverse waves have two phases:
    • Compression
    • Rarefraction

    Slide 15 - Slide

    Where do you the compression and rarefaction?

    Slide 16 - Slide

    Where do you the compression and rarefaction?
    Compression

    Slide 17 - Slide

    Where do you the compression and rarefaction?
    Compression
    Rarefaction

    Slide 18 - Slide

    Slide 19 - Slide

    Sound waves require a medium
    • Air (gas)
    • Water (liquid)
    • Metal (solid)

    Slide 20 - Slide

    Sound waves require a medium
    • Air (gas) — 343 m/s
    • Water (liquid) — 1500 m/s
    • Metal (solid) — 5100 m/s
