Driven Oscillator

 

Driven Oscillator Demo Picture

When the sine wave generator is tuned to the right freequency ( the natural frequency of the mass-spring system) the mass oscillates with very large amplitude. When generator is not tuned to the natural frequency of the spring (even if off by .1 Hz), oscillation amplitude is very small.

Pendulum Wave

 

Pendulum Wave Demo Picture

  • Aesthetic demonstration based on relationship between period and arm length.
  • Use wooden slat to start pendula in unison with equivalent
    amplitudes. As pendula cycle through all possible phase relationships, a variety
    of wave patterns emerge.
  • Located in L02, section C-1.
