ЧТО ОЗНАЧАЕТ СЛОВО TRAVELLING WAVE
Волна
В физике волна представляет собой возмущение или колебание, которое проходит через материю / пространство, сопровождающееся передачей энергии. Волновое движение передает энергию из одной точки в другую, часто без постоянного смещения частиц среды, то есть с небольшим массовым транспортом или без него. Вместо этого они состоят из колебаний или вибраций вокруг почти фиксированных мест. Волны описываются волновым уравнением, которое определяет, как возмущение протекает со временем. Математическая форма этого уравнения варьируется в зависимости от типа волны. Существует два основных типа волн. Механические волны распространяются через среду, и вещество этой среды деформируется. Деформация меняет себя из-за восстановления сил, возникающих в результате ее деформации. Например, звуковые волны распространяются через молекулы воздуха, сталкивающиеся со своими соседями. Когда молекулы воздуха сталкиваются, они также отскакивают друг от друга. Это препятствует продолжению движения молекул в направлении волны. Второй основной тип волн, электромагнитных волн, не требует среды.
