A focused three-component revision and exam practice pack for SP5f, covering the complete Edexcel Separate Science Physics specification for applications of radio waves, microwaves, infrared and visible light (P5.22a–d, P5.23).

Topic Mastery Sheet covers all required uses of radio waves, microwaves, infrared and visible light with sufficient detail to answer Edexcel exam questions; Higher tier content on how radio waves are produced and detected, and why certain materials are not suitable as detectors; and how optical fibres transmit data using the principle of total internal reflection. The difference between how microwave ovens and infrared grills heat food is explained at the particle level.

Student Exam Practice Sheet includes a table-completion exercise on uses of four EM wave types, a Higher tier question on radio wave detection requiring a three-step explanation, a question on optical fibre data transmission, and a question comparing microwave oven and infrared grill heating. Question format matches the Edexcel test style.

Teacher Answer Key provides a complete mark scheme with the three specific steps required for the detector question and guidance on what the optical fibre question requires for each mark.
