Sonoluminescence is the emission of light by bubbles in a liquid excited by sound.

Four steps are presented :

1. apparition of bubble 2. quick expansion 3. sudden contraction (very short compared to expansion) 4. light produced by the high pressure and high temperatures inside the small bubble

Drawn with Inkscape 0.42 (full of bugs) and Gimp (that I don't like much)
