📋 What it is
A wave thinker predicts how a wave travels, reflects and interferes, then checks it against what they hear or see.
🗣️ Coach says
This is the whole wave mindset. Given any wave — sound, light, radio, water — you can predict how fast it goes, how it bounces, bends and overlaps, then test your prediction. The best thinkers connect one tiny ripple to whole technologies like music, imaging and communication.
🧠 Memory hook
Predict a wave’s path (travel · reflect · interfere) → test → refine. One ripple → whole tech.

Why did the echo feel unoriginal?
Because it just repeated what everyone else said!
😲 Whoa!
Doctors "see" a baby before birth using ultrasound — sound waves too high to hear, bounced off the body and turned into a picture.
✅ Quick check: How does an ultrasound scan make a picture without light?
Say your answer out loud first — then reveal.
It sends high-frequency sound into the body and maps the echoes that bounce back into an image.
Ultrasound uses reflected sound waves, not light, to image.
🧪 Try it! (2 minutes)
Predict what happens to a shout in a big empty room, then test it — echoes are reflected sound.
