Cross-Topic Connections
📋 What it is
Optics topics link: reflection, refraction and colour are all the same light behaving in different situations.
🗣️ Coach says
The optics ideas connect into one story. Reflection, refraction, dispersion and colour are all just LIGHT interacting with materials in different ways. A lens, a rainbow, a mirror and a fibre-optic cable all use the same handful of rules. Linking them is how you really understand light.
🧠 Memory hook
One set of rules — bounce, bend, split — explains mirrors, lenses, rainbows AND fibre optics.
😂 Giggle
What did the mirror say to the incoming light ray?
"I see you've come to reflect on things!"
😲 Whoa!
A rainbow and the glare off a car window use the SAME physics (light bending and bouncing) as the lens in your own eye.
✅ Quick check: What do a mirror, a lens and a rainbow have in common?
Say your answer out loud first — then reveal.
All are light behaving by the same rules — bouncing (reflection) or bending (refraction/dispersion).
A few optics rules explain many different effects.
