Named after Heinrich Geissler (1814–79), German mechanic.
QUÉ SIGNIFICA GEISSLER TUBE EN INGLÉS
Tubo geissler
Un tubo de Geissler es un tubo de descarga de gas temprano usado para demostrar los principios de la descarga de luz eléctrica. El tubo fue inventado por el físico alemán y soplador de vidrio Heinrich Geissler en 1857. Se compone de un cilindro de vidrio sellado, parcialmente evacuado de varias formas con un electrodo de metal en cada extremo, que contiene gases rarificados como neón, argón o aire; Vapor de mercurio u otros fluidos conductores; O minerales o metales ionizables, tales como sodio. Cuando se aplica una alta tensión entre los electrodos, una corriente eléctrica fluye a través del tubo. La corriente disocia electrones de las moléculas de gas, creando iones, y cuando los electrones se recombinan con los iones, el gas emite luz por fluorescencia. El color de la luz emitida es característico del material dentro del tubo, y se pueden lograr muchos colores y efectos de iluminación diferentes. Las primeras lámparas de descarga de gas, los tubos de Geissler eran artículos de la novedad, hechos en muchas formas y colores artísticos para demostrar la nueva ciencia de la electricidad. A principios del siglo XX, la tecnología fue comercializada y evolucionó a la iluminación de neón.
definición de Geissler tube en el diccionario inglés
La definición de tubo de Geissler en el diccionario es un vaso de vidrio o cuarzo, que generalmente tiene dos bombillas que contienen electrodos separados por un tubo capilar, para mantener una descarga eléctrica en un gas a baja presión como fuente de luz visible o ultravioleta para espectroscopía.
