En esta ocasi\u00f3n, te traigo una emocionante gu\u00eda para experimentar en casa este misterio cotidiano llamado Efecto Doppler, \u00a1y solo necesitas tu tel\u00e9fono m\u00f3vil!<\/p>\n<h3>\u00a1Explora el misterio del sonido! Gu\u00eda para experimentar el Efecto Doppler en casa<\/h3>\n<p>El Efecto Doppler es el fen\u00f3meno por el cual la altura de un sonido (el tono) cambia cuando la fuente que lo emite est\u00e1 en movimiento.<\/p>\n<p>El sonido viaja como vibraciones en el aire, es decir, como ondas. Cuando la fuente de sonido se acerca a nosotros, las ondas se comprimen porque la fuente &#8220;empuja&#8221; las ondas anteriores, haciendo que el espacio entre ellas sea m\u00e1s corto (la longitud de onda disminuye). Por el contrario, cuando se aleja, las ondas se estiran como si se quedaran atr\u00e1s (la longitud de onda aumenta).<\/p>\n<p>Nuestros o\u00eddos perciben las ondas apretadas como un sonido agudo y las ondas estiradas como un sonido grave. Por lo tanto, el cambio en la sirena de la ambulancia no es porque el sonido cambie en s\u00ed mismo, sino porque cambia la forma en que las ondas llegan comprimidas a nuestros o\u00eddos.<\/p>\n<p>Primero, comparemos la diferencia en este video. Presta atenci\u00f3n a c\u00f3mo suena el paso a nivel desde fuera y desde dentro del tren.<\/p>\n<p><iframe loading=\"lazy\" title=\"\u8e0f\u5207\u97f3\u3068\u30c9\u30c3\u30d7\u30e9\u30fc\u52b9\u679c\uff08\u96fb\u8eca\u306b\u4e57\u3063\u3066\u805e\u3044\u3066\u307f\u305f\uff09\" width=\"1140\" height=\"641\" src=\"https:\/\/www.youtube.com\/embed\/q9fWzDpsfSw?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>Y aqu\u00ed tienes el cambio de sonido justo cuando una ambulancia real pasa de largo.<\/p>\n<p>https:\/\/www.youtube.com\/watch?v=CdWV76rqPso<\/p>\n<p>\u00bfQu\u00e9 te ha parecido?
