Physics 2.3 Demonstrate understanding of wave phenomena
Achievement criteria
The level of performance that you will gain will be determined by the complexity of the questions, and how you answer them. You need to be able to describe and explain wave phenomena and use mathematical methods to solve problems. Minor errors (computational or transcription) will not be penalised if the process used to determine the solution is clearly indicated and is valid.
Achievement
Make sure you can:
- identify or describe aspects of phenomena, concepts, or principles
- solve straightforward problems which involve a single-step process
- produce clear, neat and accurate diagrams of light rays and waves
- identify and describe straightforward wave phenomena such as diffraction, refraction and reflection using correct physics terminology.
Achievement with Merit
Make sure you can:
- give accurate explanations in terms of phenomena, concepts, principles, and/or relationships.
- solve problems that may involve using a complex formula or rearrangement or some deduction as to the relevant concept or principle is required.
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!
- use diagrams and written explanations to explain complex wave phenomena such as two-point interference
- solve complex problems which will involve more than one process and concept
- show numerical accuracy, correct rounding, and use SI units in answers.
