PocketLab/Phyphox Damped Lissajous Figures
Lissajous Introduction
Lissajous patterns have fascinated physics students for decades. They are commonly observed on oscilloscopes by applying simple harmonic functions with different frequencies to the vertical and horizontal inputs. Three examples are shown in Figure 1. From left to right, the frequency ratios are 1:2, 2:3, and 3:4. These Lissajous patterns were created by use of the parametric equation section of The Grapher software written by the author of this lesson. You are welcome to use this softwa
