The terms in bold link to topics in the AQA, Edexcel, OCR, WJEC and CCEA A-level specifications, as well as the IB, Pre-U and SQA exam specifications. When analysing diffraction by a single slit, we can use phasors (rotating vectors) to represent wave amplitude and phase.
The wave nature of light and how it diffracts through a single slit and interferes through multislits can be explained using a special type of vector called a phasor.
