Waves- Transverse & Longitudinal, the wave equation

• Oscillation / Vibration

  • How energy is transferred through waves around a rest position
• Amplitude of a wave

  • It's height
  • Measured from rest to crest in meters (m)
• Wavelength

  • The distance from one point on a wave to the same point on the next wave
  • measured in meters (m) and given the symbol λ
• Frequency of a Wave

  The number of complete waves that occur in 1 second

  • Measured in Hertz (Hz) and given the symbol f.
  • Energy is transferred, not particles, particles oscillate in a fixed position.

  A) Amplitude

  B) Crest

  C) Wavelength

  D) Trough

  E) Crest

  F) Wavelength

  G) Trough

  
• Frequency Equation

  Frequency = 1/time (s)
• Speed / Velocity

  • How fast a wave travels in a given time
  • Measured in meters per second (m/s) and given the symbol v.
• Time Period

  • How long it takes for one complete wave to pass a certain point.
  • Measure in seconds (s) and given the symbol T.
• Wavefront

  • Visualises waves from above.
  • Drawn to imagine the vibrating part of a wave
  • When close together, wavelength is short.

  
• Period (T)

  Time taken for one full cycle to pass (in s)
• Oscillation

  One full wave cycle
• Wave Speed

  Speed of a wave in standard units (m/s)
