Standing Wave in a Pipe (n=3)

p(x,t) = sin(nπx/L)·cos(ωt), n = 3
Standing Wave in a Pipe (n=3)

The third resonant mode of an air column: the pressure antinodes swell and collapse in place while the fixed nodes never move, the whole pattern breathing at the driving frequency.

Computed & rendered in pure C# on the frozen OnlyCSharp 1.8 library — animation baked to GIF with the library's own Gif encoder (no GPU, no ffmpeg, no external packages).
