Coupled Oscillators and Normal Modes
5
Superposition of normal modes of oscillation with
different amplitudes can produce very complex
oscillation patterns This Example shows 8
normal modes of oscillation that where excited in
a given string with different amplitudes

  • Normal Modes of a String in a particular pattern
    of wave motion
  • First eight contributing normal modes of string
    with fixed ends.
  • This is equivalent to two identical traveling
    waves moving in opposite directions.
