Monochord / Sonometer

This interactive simulator explores Monochord / Sonometer in Waves & Sound. f₁ = (1/2L)√(T/μ), harmonics, note label, Pluck; vs Standing Waves shapes. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: Suited to beginners and first exposure to the topic. Typical context: Waves & Sound.

How it works

A **monochord / sonometer** idealizes a string between two bridges: wave speed **c = √(T/μ)** from tension and linear density, and **fₙ = nc/(2L)** for harmonics on a fixed–fixed string. **Standing Waves** in this lab emphasizes mode shapes; this simulator ties **L, T, μ** to **pitch** and optional **Pluck** tone.

Key equations

f₁ = (1/2L) √(T/μ), fₙ = n f₁, λₙ = 2L/n
