Puede que pienses que los equipos de laboratorio son caros, \u00a1pero en realidad puedes hacer experimentos sorprendentemente serios con art\u00edculos cotidianos! Hoy, te presento un dispositivo para experimentar con las &#8220;ondas estacionarias&#8221; (teij\u014dha), donde una cuerda parece bailar como un ser vivo. En colaboraci\u00f3n con el Profesor I de nuestra escuela, hemos desarrollado un equipo de alto rendimiento y bajo costo utilizando art\u00edculos de tiendas de 100 yenes. \u00a1Es perfecto tanto para profesores como para proyectos de ciencias en casa!<\/p>\n<h3>Receta cient\u00edfica: \u00a1Crea un dispositivo de experimento con cosas de casa!<\/h3>\n<p>Cuando se trata de &#8220;experimentos de f\u00edsica&#8221;, no necesitas herramientas especiales. Estos son los art\u00edculos que hemos preparado. El costo total es, de hecho, similar al de un almuerzo.<\/p>\n<p>Lo que necesitas: Un altavoz barato (que luego desmontaremos). Por ejemplo, el que compramos en Daiso por 300 yenes era potente. Como tiene una potencia de 3W, puede hacer vibrar la cuerda con m\u00e1s fuerza y dinamismo. En los experimentos cient\u00edficos, \u00a1la parte emocionante es encontrar mejores piezas y mejorar el equipo!<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-33664\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2019\/08\/IMG_0271.jpg\" alt=\"\" width=\"800\" height=\"600\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2019\/08\/IMG_0271.jpg 800w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2019\/08\/IMG_0271-300x225.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2019\/08\/IMG_0271-768x576.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/p>\n<p>\u30fb Hilo de cocina (bramante) \u30fb Pesas (pueden ser de pesca o un manojo de monedas de 5 yenes) \u30fb Soporte para tablas de cortar (comprado en una tienda de 100 yenes)<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-26251 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/11\/70f918fbcb349802dbf9ff2366944a1e.jpg\" alt=\"%e3%82%b9%e3%82%af%e3%83%aa%e3%83%bc%e3%83%b3%e3%82%b7%e3%83%a7%e3%83%83%e3%83%88-2016-11-07-17-30-49\" width=\"185\" height=\"330\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/11\/70f918fbcb349802dbf9ff2366944a1e.jpg 309w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/11\/70f918fbcb349802dbf9ff2366944a1e-168x300.jpg 168w\" sizes=\"auto, (max-width: 185px) 100vw, 185px\" \/><\/p>\n<p>\u30fb Cargador de pared USB (comprado en una tienda de 100 yenes)<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-26252 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/11\/c16b1415887483947159a5501f338754.jpg\" alt=\"%e3%82%b9%e3%82%af%e3%83%aa%e3%83%bc%e3%83%b3%e3%82%b7%e3%83%a7%e3%83%83%e3%83%88-2016-11-07-17-31-08\" width=\"388\" height=\"397\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/11\/c16b1415887483947159a5501f338754.jpg 388w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/11\/c16b1415887483947159a5501f338754-293x300.jpg 293w\" sizes=\"auto, (max-width: 388px) 100vw, 388px\" \/><\/p>\n<p>\u30fb Un smartphone o iPad como fuente de sonido (Aseg\u00farate de tener una aplicaci\u00f3n gratuita de &#8220;generador de tonos&#8221;.

Al usar la app para cambiar el sonido emitido por el altavoz, desde un tono grave (baja frecuencia) hasta uno agudo, en el instante en que alcanza una frecuencia espec\u00edfica, la cuerda comienza a agitarse violentamente, creando una hermosa forma de onda. Este es el fen\u00f3meno de la &#8220;Resonancia&#8221; (ky\u014dshin) en f\u00edsica, y la forma de onda &#8220;inm\u00f3vil&#8221; que se produce en ese momento es la &#8220;onda estacionaria&#8221;.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-26248 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/11\/7c5b93c11b055e9313503f1c445b6420.jpg\" alt=\"%e3%82%b9%e3%82%af%e3%83%aa%e3%83%bc%e3%83%b3%e3%82%b7%e3%83%a7%e3%83%83%e3%83%88-2016-11-07-17-29-23\" width=\"639\" height=\"481\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/11\/7c5b93c11b055e9313503f1c445b6420.jpg 639w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/11\/7c5b93c11b055e9313503f1c445b6420-300x226.jpg 300w\" sizes=\"auto, (max-width: 639px) 100vw, 639px\" \/><\/p>\n<p>Consejos para el \u00e9xito del experimento: Es dif\u00edcil encontrar la &#8220;vibraci\u00f3n fundamental (un solo bucle de onda)&#8221; de inmediato. Primero, ajusta la frecuencia y busca la tercera o cuarta arm\u00f3nica (cuando hay 3 o 4 &#8220;vientres&#8221; en la onda). Estos son relativamente f\u00e1ciles de encontrar. El truco es partir de ah\u00ed, predecir, y luego bajar la frecuencia para probar con la segunda arm\u00f3nica y, finalmente, la vibraci\u00f3n fundamental. A veces, la vibraci\u00f3n fundamental tarda un poco en formarse completamente despu\u00e9s de que el sonido comienza a emitirse y la cuerda se agita, as\u00ed que ten paciencia.<\/p>\n<h3>El toque del profesional: T\u00e9cnicas de modificaci\u00f3n para reducir el ruido<\/h3>\n<p>Hace poco visit\u00e9 Narika y vi su equipo para observar ondas estacionarias en cuerdas (<a href=\"http:\/\/www.rika.com\/product\/prod_detail1.php?catalog_no=C15-4389\">Conjunto de experimento de ondas estacionarias<\/a>). Como era de esperar, a diferencia del equipo casero, este ten\u00eda m\u00e1s potencia y permit\u00eda observar ondas estacionarias muy n\u00edtidas.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-33699 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2019\/09\/5.jpg\" alt=\"\" width=\"386\" height=\"239\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2019\/09\/5.jpg 386w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2019\/09\/5-300x186.jpg 300w\" sizes=\"auto, (max-width: 386px) 100vw, 386px\" \/><\/p>\n<p>Tambi\u00e9n es interesante que al colocar el dispositivo vibrador en posici\u00f3n vertical, la frecuencia de vibraci\u00f3n se reduce a la mitad.

Imitando esto, prob\u00e9 a poner la parte vibratoria del dispositivo de Daiso que hice yo mismo hacia arriba y a usar una regla o similar.
