Waves requirements

Achievement Make sure you can: Identify or describe aspects of phenomena, concepts, or principles. Solve straightforward problems which involve a single-step process. Recognise correct concept/phenomenon/principle and give a simple descriptive answer in both written and diagrammatic form, for example: the Doppler effect standing waves in strings and air columns harmonics why the same note played on one instrument sounds different on another instrument. Recognise the correct concept and apply reasonable mathematical skills, for example, calculating the nth order maximum for diffraction grating interference pattern. Achievement with Merit Make sure you can: Meet criteria for Achievement. Give accurate explanations in terms of phenomena, concepts, principles, and/or relationships. Solve problems which may involve using a complex formula or rearrangement or some deduction as to the relevant concept or principle. Achievement with Excellence Make sure you can: Give concise and accurate explanations that show clear understanding in terms of phenomena, concepts, principles, and/or relationships. Your answers will typically have minimal irrelevancies. In other words, you cannot include any explanations that are not relevant. Do not guess! Solve complex problems which will involve more than one process and concept. Show numerical accuracy, correct rounding and use SI units in answer
