Demo Title: Lissajous Figures - Oscilloscope
Condition: Excellent
Principle: Lissajous Figures
Area of Study: Oscillations & Acoustics
Equipment:
Tektronix 2235 Oscilloscope, Wave Generators (2) (Preferably the Wavetek digitals), and Video Camera with Power Supply.
Procedure:
Plug one wave generator into each input of a dual trace scope. Set the oscilloscope to X - Y plotting. If each generator is at the same frequency the figure will be in the form of a circle. More complicated patterns will be obtained with higher harmonic frequencies. The Wavetek generators work much better for this because they are more stable and they also have a 'stabilization mode' so that you can lock onto a desired frequency.
