IGCSE Physics Waves Unit Bundle — 7 Full Lessons [0972/0625]

A complete, classroom-ready bundle covering every topic in the Waves unit for Cambridge IGCSE (9-1) Physics (0972/0625). This bundle includes all seven full lessons, each featuring an editable PowerPoint with full explanation slides, guided practice, retrieval tasks, Q&A, and model answers — fully aligned to the 0972/0625 specification.
Included lessons:

3.1 General Properties of Waves — wave terminology, transverse vs longitudinal waves, wave equation (v = fλ), reflection, refraction, diffraction, ripple tank demonstrations

3.2.1 Reflection of Light — law of reflection, plane mirror images, ray diagram construction, virtual image characteristics

3.2.2 Refraction of Light — Snell’s Law, refractive index, critical angle, total internal reflection, optical fibres and endoscopes

3.2.3 Thin Lenses — converging and diverging lenses, ray diagrams, image characteristics table, magnifying glass, long and short-sightedness correction

3.2.4 Dispersion of Light — dispersion through a prism, visible spectrum in order of frequency and wavelength, monochromatic light

3.3 Electromagnetic Spectrum — all seven regions, applications and hazards, satellite communication, digital vs analogue signals

3.4 Sound — longitudinal waves, compressions and rarefactions, speed of sound, audible range, ultrasound applications, echo calculations

Every lesson includes editable PPT slides fully aligned to the 0972/0625 spec, learning objectives matched to specification points, diagrams and conceptual visuals, retrieval and check-progress questions with model answers, exam-style practice written in Cambridge format, embedded simulations and video links, and EAL-friendly scaffolds for mixed-ability classes.
