A focused three-component revision and exam practice pack for SP5e, covering the complete Edexcel Separate Science Physics specification for the EM spectrum (P5.10, P5.11, P5.13).

Topic Mastery Sheet covers the full order of the electromagnetic spectrum with wavelength and frequency ranges; the visible spectrum in order; the continuous nature of the spectrum; how the temperature of an object affects both the intensity and peak wavelength of the radiation it emits, with reference to a radiation intensity graph; and how to read peak wavelength values from such a graph. The source of thermal radiation from hot objects is explained at the atomic level. Higher tier content on how different substances interact with different EM wavelengths is included.

Student Exam Practice Sheet includes a spectrum-ordering question with partial marking, a multiple choice question on visible light wavelengths, a two-part question on radiation from hot objects using a graph, a graph-reading question requiring comparison of values at different temperatures, and an explanation question linking EM wave properties to a medical application. Question format matches Edexcel test style.

Teacher Answer Key provides a complete mark scheme with acceptable value ranges for graph-reading questions and guidance on how the ordering question is awarded partially.
