AQA 3.3 Waves
In this section on waves there is the development of GCSE content about the properties of travelling waves. Topics include refraction, diffraction, superposition and interference as well as stationary waves.
3.3.1 Progressive and Stationary Waves
3.3.2 Refraction, Diffraction and Interference
Interference - The interaction of two or more waves
The Double Slit - Young's famous experiment that produces an interference pattern
Diffraction Gratings - Plane transmission gratings and the pattern these produce
Refraction - The changing direction of a wave as it crosses a boundary
Total Internal Reflection - TIR as a wave travels towards a different medium
Optical Fibres - These allow the modern digital world to communicate at light speed
