Revisit the 2 source interference ideas from Y12 – possibly with a web-based simulation
How to “wake up” knowledge that’s asleep
Come back to the core concept in two source interference
Why path difference is the foundation of this topic
Prove a formula that is on the resource booklet
Where n=d.sin comes from and what it means
See the difference between the formula for twin and multi slits – and how to find d if we are given N
What the difference is between the formulae ANDHow to find N or d if given the other
HRT on units 5, 6 and 7 How to do three units of learning in one period
