  4. 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 Credit: http://www.calpoly.edu/~gepstein/NormalModes/

  6. 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. Credit: http://www.calpoly.edu/~gepstein/NormalModes/

  7. 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. Partial Sum of the 8 most important normal mode contributions: Credit: http://www.calpoly.edu/~gepstein/NormalModes/
