I tried to simulate the cool visual of Pendulum Waves in Wolfram Language.
pendulum[r_,\[Theta]_,h_]:=With[{d={h,0,0},p={h,-r Sin[\[Theta]],-r Cos[\[Theta]]}},
Graphics3D[{Specularity[White,30],Red,Sphere[p,0.03],Line[{d,p}]}
,PlotRange->{{0,1},{-0.5,0.5},{(*Z*)-0.9,0}}
,ViewPoint->Left
]
]
Animate[Show[Table[pendulum[r,0.5Sin[ 2\[Pi](r) t],r],{r,0.4,0.8,0.02}],ImageSize-> 300]
,{t,0,15,0.01}
,AnimationRate->0.5
]
Here is the result:
I don't know why, but If I try to simulate using the more realist frequency (1/r), the visual effect is not so nice.
Improvments are always welcome!
