Transcript

  • 1. Characteristics of Waves
  • 2.
    • Wave - rhythmic disturbance that carry energy through matter or space.
    • There are 2 types of waves
    • Transverse Waves
    • Compressional or Longitudinal
  • 3.
    • Transverse wave- the medium moves at right angles to the direction that the wave travels. Ex: shaking a rope
  • 4.
    • Part of a transverse wave
    • Crest - highest point of the wave
    • Troughs - lowest point of the wave
    • Medium - material through which a wave transfers energy. It can be solid, liquid or gas
    • Amplitude - the distance from the crest (or trough) of the wave to the rest position of the medium.
  • 5. Medium Crest Trough
  • 6.
    • Wavelength - the distance between the point of 1 wave to the same point on another wave.
    Medium
  • 7.
    • Frequency - the number of wave crests that pass on place in a second.
    • -It is measured in hertz. (Hz)
  • 8.
    • Compressional or Longitudinal waves- the matter vibrates in the same direction as the wave travels.
    • Ex: a spring
  • 9.
    • Compression - crowded area (when the spring is together)
    • Rarefaction- expanded area (when the spring is apart)
  • 10.
    • Wavelength- made up of 1 compression and 1 rarefaction.
