Мы видим волны на воде почти каждый день, мы используем световые волны, чтобы увидеть волны на воде; мы слышим звуки с звуковых волн. Волна - движение везде. Водные волны, световые волны, звуковые волны, любые волны имеют одну общую черту. Они передают энергию через среду посредством колебаний частиц, но среда в целом не изменяется и не смещается. Число полных колебаний в секунду называется частотой волнового движения. Расстояние между вершиной одной волны и вершиной следующей (или между основанием одной волны и основанием следующей) называется длиной волны. Чтобы найти скорость волнового движения, мы умножаем частоту на длину волны. Это важное уравнение верно для любых волн.
