Bajo ciertas condiciones, esta superposici\u00f3n genera un patr\u00f3n que parece permanecer quieto. Eso es una onda estacionaria.<\/p>\n<p>Su estructura est\u00e1 formada por <b>vientres o antinodos (zonas que vibran con gran amplitud)<\/b> y <b>nodos (puntos que permanecen completamente inm\u00f3viles)<\/b>, distribuidos de forma regular. El resultado es tan elegante que parece una ola congelada en el tiempo.<\/p>\n<p>Los instrumentos de cuerda como la guitarra o el viol\u00edn pueden producir sonidos ricos y armoniosos precisamente gracias a este fen\u00f3meno.<\/p>\n<h3>Materiales necesarios<\/h3>\n<p><b>Un altavoz, un iPad, una fuente de alimentaci\u00f3n USB, tijeras, un c\u00fater y cuerda de algod\u00f3n (lo ideal es un di\u00e1metro de 1,4 mm).<\/b><\/p>\n<p>Este es el altavoz que utilic\u00e9 para el experimento.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-30583 aligncenter\" src=\"http:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2018\/01\/low_IMG_5499.jpg\" alt=\"\" width=\"394\" height=\"296\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2018\/01\/low_IMG_5499.jpg 800w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2018\/01\/low_IMG_5499-300x225.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2018\/01\/low_IMG_5499-768x576.jpg 768w\" sizes=\"auto, (max-width: 394px) 100vw, 394px\" \/> <\/p>\n<p style=\"text-align: center;\">Altavoz iBUFFALO USB, 1 W, sin necesidad de enchufe de corriente<\/p>\n<p>Tambi\u00e9n puedes usar los altavoces econ\u00f3micos que venden en Daiso por unos 300 yenes.
