Characteristics of Waves

Wave- rhythmic disturbance that carry energy through matter or space. There are 2 types of waves Transverse Waves Compressional or Longitudinal

Transverse wave- the medium moves at right angles to the direction that the wave travels. Ex: shaking a rope

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.

Crest Medium Trough

Wavelength- the distance between the point of 1 wave to the same point on another wave. Medium

Frequency- the number of wave crests that pass on place in a second. -It is measured in hertz. (Hz)

Compressional or Longitudinal waves- the matter vibrates in the same direction as the wave travels. Ex: a spring

Compression- crowded area (when the spring is together) Rarefaction- expanded area (when the spring is apart)

Wavelength- made up of 1 compression and 1 rarefaction.
