La clave est\u00e1 en <b>el tipo y la cantidad de gas que queda dentro del tubo<\/b>. Al aplicar voltaje, los electrodos emiten electrones de alta velocidad. Cuando estos electrones chocan con las mol\u00e9culas de gas restantes dentro del tubo, las mol\u00e9culas se excitan (aumentan su nivel de energ\u00eda). Luego, al volver a su estado original, <b>emiten luz<\/b>, y la longitud de onda (es decir, el color) depende del tipo de gas.<\/p>\n<p>En tubos con un bajo nivel de vac\u00edo (es decir, con m\u00e1s aire restante), mol\u00e9culas como el nitr\u00f3geno y el ox\u00edgeno participan en la emisi\u00f3n de luz, dando lugar a colores <b>rosados o anaranjados<\/b>. A medida que el vac\u00edo aumenta y disminuyen los gases residuales, la luz se vuelve <b>azulada o cercana al ultravioleta<\/b>. Cuando el vac\u00edo es extremadamente alto, los electrones chocan con las paredes internas del tubo de vidrio y se produce <b>fluorescencia (luz verde)<\/b>. Este fen\u00f3meno se conoce como \u201crayos cat\u00f3dicos\u201d y es el mismo principio de los antiguos televisores de tubo.
