Urmărește-ne pe DiscoverO undă de şoc este un tip de perturbaţie propagată care poate, uneori, chiar să depăşească viteza sunetului, potrivit BBC.
Deşi ideea că trombonul produce unde şoc a fost exprimată pentru prima dată în 1995, oamenii de ştiinţă au reuşit abia acum să filmeze procesul.
Filmuleţul a fost prezentat la reuniunea Societăţii Americane de Acustică în Seattle, SUA.
Undele de şoc se formează atunci când aerul este suflat în trombon deosebit de puternic - în limbaj muzical, "fortissimo" şi "fortississimo".
