Lenses [Triple Only]
Waves training before the targeted original question drill.
Adaptive teaching card
Make it concrete
Analogy
Lenses [Triple Only] is like tracking a system with arrows and numbers: decide what changes, what stays conserved, and what equation describes it.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
Lenses [Triple Only] sits inside Waves, so learn the core definition and the exam example that usually comes with it.
Focus on the model, equation, graph or force/energy transfer that explains the change when revising lenses.
For a longer answer, write the equation or model first, then use units, graph clues or direction carefully.
