Description
When viewed through a spectroscope, this spectrum tube reveals the characteristic spectral lines of hydrogen and helium. Combining hydrogen and helium in a tube allows students to measure the spectral lines of the two most commonly used elements in studying stellar evolution. The tube design concentrates the gases in the center for better brilliance. Tube is 25 cm L with termination caps at each end. Requires Spectrum Tube Power Supply (item #755400, not supplied).
Spectrum Tube, Hydrogen and Helium. When viewed through a spectroscope, spectrum tubes reveal the characteristic spectral lines of elements. Like a fingerprint, these lines identify elements and enable astronomers to study the comparison of stars, galaxies, and even the universe.
Hydrogen and helium are the 2 most abundant elements in the universe. Combining hydrogen and helium allows students to measure spectral lines commonly used in studying stellar evolution. Measuring the line spectra of hydrogen and helium is a good introduction to spectroscopic analysis, allowing students to distinguish 2 different spectral signatures.
The tube design concentrates the gases in the center for better brilliance. Tube is 25 cm L with termination caps at each end. Requires Spectrum Tube Power Supply (item #755400, not supplied).
