WebThe NexGen Spectrum Tube System offers a considerable improvement in safety, convenience, and tube life over conventional systems. Conventional spectrum tubes require a "30 seconds on, 30 seconds off" power cycle, but these "electrodeless" tubes does not have that limitation. This feature lets students take their time measuring spectral emissions. WebHe discovered that light is made up of a spectrum of seven distinct visible colors. This spectrum of colors always appears in the same order. You can see this color spectrum (Red, Orange, Yellow, Green, Blue, Indigo, Violet and all the colors in between) when you look through a diffraction grating.
