ETIMOLOGIA DELLA PAROLA GEISSLER TUBE
Named after Heinrich Geissler (1814–79), German mechanic.
CHE SIGNIFICA GEISSLER TUBE IN INGLESE
Tubo Geissler
Un tubo Geissler è un primo tubo di scarico del gas utilizzato per dimostrare i principi di scarico elettrico. Il tubo è stato inventato dal fisico tedesco e da vetro Heinrich Geissler nel 1857. È costituito da un cilindro di vetro sigillato e parzialmente evacuato di varie forme con un elettrodo di metallo ad ogni estremità contenente gas rarefatti come neon, argon o aria; Vapore di mercurio o altri fluidi conduttivi; O minerali ionizzabili o metalli, come il sodio. Quando un'alta tensione viene applicata tra gli elettrodi, una corrente elettrica scorre attraverso il tubo. L'attuale dissociata gli elettroni dalle molecole di gas, creando ioni e quando gli elettroni ricombinano con gli ioni, il gas emette luce dalla fluorescenza. Il colore della luce emessa è caratteristico del materiale all'interno del tubo e si possono ottenere diversi colori e effetti luminosi. Le prime lampade a gas, i tubi Geissler erano articoli di novità, realizzati in molte forme e colori artistici per dimostrare la nuova scienza dell'elettricità. All'inizio del XX secolo, la tecnologia è stata commercializzata e si è evoluta in illuminazione al neon.
definizione di Geissler tube nel dizionario inglese
La definizione di Geissler tube nel dizionario è un vaso di vetro o quarzo, di solito con due bulbi contenenti elettrodi separati da un tubo capillare, per mantenere una scarica elettrica in un gas a bassa pressione come fonte di luce visibile o ultravioletta per la spettroscopia.
