📋 What it is
Optics powers everyday life — screens, cameras, lasers, glasses, barcode scanners and medical scopes.
🗣️ Coach says
Light technology is everywhere. Screens mix RGB light, cameras and phones use lenses, lasers read discs and scan barcodes, glasses and contacts correct vision, and doctors use fibre-optic scopes to see inside the body without surgery. Optics quietly runs modern life.
🧠 Memory hook
Optics → screens, cameras, lasers, glasses, scanners, medical scopes.
