Oscillations & Waves

Summary

This Year 9 unit begins with the simplest repeating motion — a swinging pendulum — and builds towards the waves that carry energy through ropes, water and air. Students measure period and frequency, model transverse and longitudinal waves, and finish by asking why matching a system’s natural frequency can shake a bridge apart.
