📋 What it is
Everyday life is full of wave science — music, hearing, phones, medical scans and Wi-Fi.
🗣️ Coach says
Once you know waves, you can explain a huge slice of daily life: how earbuds play music, why a concert hall sounds good, how a phone connects, how a doctor scans a baby, and how Wi-Fi fills a room with data. Waves are one of the most useful ideas in all of science.

What did the photon say when asked if it had mass?
"I'm light — I travel light!"
😲 Whoa!
Your ears can detect a vibration so tiny it moves your eardrum less than the width of a single atom — one of the most sensitive detectors in nature.
✅ Quick check: Name one everyday thing that depends on wave science.
Say your answer out loud first — then reveal.
Music/earbuds, phone calls, Wi-Fi, or medical ultrasound — all use waves.
Waves underpin audio, communication and imaging.
