# standing waves
A standing wave forms when a wave reflects back on itself and locks into a fixed pattern of nodes and antinodes — it's why a guitar string rings at a specific pitch and why a room can boom at one frequency and swallow another. With eight simulations, this is one of the site's deepest wave-physics tags: String Physics — Vibrating String & Harmonics and String Vibration — Standing Waves and Harmonics both let you pluck a string and watch its harmonic modes stack up, while Drum Membrane Vibration renders the two-dimensional version as Chladni patterns on a vibrating membrane. Standing Waves in Pipes covers the acoustic resonance behind wind instruments, and four separate room-acoustics simulations — Room Modes, Room Acoustics, Room Acoustics (RT60, Modes & Flutter Echo) and Acoustic Room Modes — model how standing waves build up inside a physical room.

📊 Facts
How many standing-wave simulations are here?
8 simulations — the largest single cluster covers room acoustics, with four separate simulations of standing waves inside a room.
What are Chladni patterns and where can I see them?
Drum Membrane Vibration — 2D Wave Equation & Chladni Patterns renders the sand-on-a-vibrating-plate patterns that appear where a 2D membrane's standing waves cancel out.
Which sims cover vibrating strings?
String Physics — Vibrating String & Harmonics and String Vibration — Standing Waves and Harmonics both let you pluck a string and see its fundamental and overtones.
Why four different room-acoustics simulations?
Room Modes, Room Acoustics, the RT60/Flutter-Echo version and Acoustic Room Modes each model a different aspect of how standing waves build up in enclosed spaces.
