P1.5 Waves

P1.5 Waves

1. Waves can be described by their:

   • Frequency
     • The number of waves passing each second. Measured in hertz(Hz)
   • Speed
     • Measured in m/s
   • wavelength
     • From peek to peek
   • Amplitude
     • Half of the distance from peek to bottom.

2. Longitudinal

   • Example: Sound waves and seismic P waves
   • Movement : they move back and forth to the direction of the energy transfer.
   • LONGitudenal waves move aLONG the same direction

3. Transverse

   • Example : water surface, electromagnetic waves and seismic S waves
   • Movement : they move at a right angle to the way that the wave is travelling
   • tranSverSe waves move acroSS.
