A focused three-component revision and exam practice pack for SP5a, covering the complete Edexcel Separate Science Physics specification for ray diagrams including the core practical (SP5.1P, SP5.9).

Topic Mastery Sheet covers the law of reflection with precise angle conventions; refraction at a glass block including how to draw the correct ray path and why the emergent ray has a specific relationship to the incident ray; a step-by-step description of the core practical method for investigating refraction; total internal reflection including the conditions required and how to determine whether TIR is occurring; and a range of real-world applications. The data anomaly present in the standard unit test refraction dataset is identified and explained.

Student Exam Practice Sheet includes a multiple choice question on wavelength of visible light, a reflection diagram question with angle calculation, a 4-mark practical method question, a data analysis question requiring identification and explanation of an anomalous result, and a 3-mark TIR description question. Question format matches the Edexcel unit test.

Teacher Answer Key provides a complete mark scheme including guidance on how the anomalous result question is credited and what level of detail is required for the core practical method.
