Key Definitions:

  • Wavefront: Created by overlapping lots of different waves. A wavefront is where all the vibrations are in phase and the same distance from the source.
  • Amplitude: The maximum displacement of particles from their equilibrium position.
  • Wavelength: The distance between a particular point on one cycle of the wave and the same point on the next cycle.
  • Frequency: The number of waves passing a particular point per second. Is measured in Hertz (Hz).
  • Time Period: The time it takes for one complete wave to pass a particular point.
