IGCSE Physics - Waves - With Exam Q and As

These slides cover the essential theoretical concepts of Waves for the IGCSE Physics KS4 curriculum. They focus on building conceptual understanding of light, sound, and the electromagnetic spectrum, without the mathematical calculations. This is to assist students who may struggle with the abstract concepts, although might be strong in the maths.

Topics Included:

• Wave Properties: Key theory for Light and Sound.
• Optics: Refraction, Dispersion, and Total Internal Reflection (TIR).
• Lenses: Comparison of Convex and Concave types.
• EM Radiation: Full breakdown of the spectrum and its practical uses.

Edexcel past paper questions are embedded throughout the slides to check understanding and practice exam technique. But lesson could be applied to any exam board.
