### 1 characteristics of waves

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