Wonderful WavesWonderful Waves!

What is a wave? Everyday waves How do we make waves? Sound and Light Scary Monster waves

Sound-wave miracle: a Tuvan musician can sing two(or three!) notes at once

Waves on waves ....

... on waves ...

... on barriers ...

. . . . to understand How we can use X-ray waves . . . .

Sensitive photo-film goes dark where X-rays hit

DNA

Another kind of wave: the bubble wobble

Some monster Waves:

Rogue sea waves

Tsunamis

Shock waves

Supernova blasts

Rogue or “freak” waves can sink a ship!

The tsunami

Sonic shock in a wind tunnel

Sonic shock wavesSonic shock wavesfrom from planesplanes

Supernova Blast Wave: the star maker

It is a wave? It is a shock?

No: it's a Smoke Ringor

vortex structure

Blast, shock, sound, and “smoke rings” — in one event
