Waves Simulation — Description & Classroom Activity Guide
Frequency & Waves Simulation — ClassAdapt Physics
This browser-based interactive simulation lets pupils explore wave properties in real time across four modes: Transverse, Longitudinal, Standing Wave, and Superposition. Sliders control frequency (0.2–5 Hz), amplitude, and wave speed, with a live metrics bar displaying wavelength, period, and wave speed calculated from v = fλ. A measure tool overlays a λ marker directly on the wave, and an explanation drawer slides up on demand with key formulae and definitions. Full SEND accessibility is built in — Irlen overlays, colour vision modes, high contrast, dyslexia spacing, reduce motion, TTS, and full keyboard navigation.

Objective: Investigate the wave equation v = fλ using the simulation as a live experiment.
Phase 1 — Hook (5 min) Project the simulation. Move the frequency slider without comment. Ask: “What changes? What stays the same?” Take responses — don’t confirm yet.
Phase 2 — Explore (15 min) Pupils manipulate frequency, amplitude, and speed independently and answer:
- What happens to wavelength as frequency increases?
- Does changing amplitude affect wave speed?
- Switch to Longitudinal — which way do particles move?
Phase 3 — Calculate (10 min) Pupils record three different frequency settings from the metrics bar and verify v = fλ by hand. The simulation confirms their answer instantly.
Phase 4 — Superposition (8 min, Higher) Set two identical frequencies → observe doubled amplitude. Diverge them → observe beating. Ask: “Why does the resultant disappear at certain points?”
Phase 5 — Exit Ticket (5 min)
In one sentence: difference between transverse and longitudinal.
f = 2 Hz, λ = 5 m → find v
v = 340 m/s, f = 170 Hz → find λ
