se produce Echo?

Oglinzile vor curge imaginile și trimit lumina înapoi. Zidurile, de asemenea, trimite vocile înapoi. Dacă stai un pic mai departe de un zid înalt sau o stâncă mare, veți auzi vocea ta filare înapoi câteva secunde mai târziu.

În cazul în care un val de sunet întâlnește un perete sau o suprafață de stâncă mare și largă, se rotește înapoi spre sursa sa. Așa se întâmplă ecoul. Dacă sunetul extras este scurt și undele sonore ajung la baterie ca de obicei, ecoul este auzit clar. Urmele sunetului rămân în ureche timp de 1/10 secunde.

Deoarece viteza sunetului în aer este de 340 metri pe secundă, distanța dintre sursa audio și bateria pentru a fi un ecou trebuie să fie de cel puțin 17 metri.
