Tanto la luz del sol como la de una linterna parecen comportarse as\u00ed, \u00bfverdad? Pero aqu\u00ed viene una pregunta fascinante: \u201c\u00bfLa luz es una part\u00edcula\u2026 o una onda?\u201d. Este misterio enfrent\u00f3 a Newton y Huygens desde el siglo XVII y se convirti\u00f3 en uno de los mayores debates de la f\u00edsica. Y lo m\u00e1s sorprendente es que puedes comprobar la respuesta en casa usando solamente un vaso de papel, un c\u00fater y un puntero l\u00e1ser de unos 2000 yenes.<\/p>\n<p>Hoy vamos a realizar un experimento de \u201cinterferencia de la luz\u201d, con el que podr\u00e1s ver con tus propios ojos que la luz se comporta como una onda. Aunque suene complicado, es una actividad perfecta para hacer con ni\u00f1os de primaria o para ense\u00f1ar en clase qu\u00e9 significa realmente una \u201conda\u201d. \u00a1Vamos a probarlo!<\/p>\n<h3>\u00bfPor qu\u00e9 sabemos que la luz es una onda? El secreto del experimento<\/h3>\n<p>La clave est\u00e1 en hacer una \u201crendija muy fina\u201d con el c\u00fater. Las ondas tienen una propiedad curiosa: cuando atraviesan un espacio estrecho, se expanden al otro lado. A esto se le llama <b>difracci\u00f3n<\/b>. Quiz\u00e1 hayas visto c\u00f3mo las olas del mar se abren en abanico al pasar entre los huecos de un rompeolas. Pues la luz hace exactamente lo mismo.<\/p>\n<p>Adem\u00e1s, la peque\u00f1a grieta hecha en el vaso de papel act\u00faa en realidad como si fueran \u201cdos rendijas extremadamente cercanas\u201d. El grosor de la cuchilla y las irregularidades del papel crean este efecto. La luz que atraviesa esas rendijas se difracta y luego se superpone sobre la pared.<\/p>\n<p>Cuando las crestas de las ondas coinciden, la luz se refuerza y aparece una zona <b>brillante<\/b>. Cuando una cresta y un valle se encuentran, se cancelan y aparece una zona <b>oscura<\/b>. As\u00ed nacen las famosas <b>franjas de interferencia<\/b> que veremos en este experimento.<\/p>\n<p>Si la luz fuera simplemente un conjunto de part\u00edculas, solo ver\u00edamos proyectada la forma de la rendija. El hecho de que aparezcan franjas es precisamente la prueba de que la luz tiene naturaleza ondulatoria.<\/p>\n<h3>\u00a1Hazlo en casa!
