In physics classrooms teaching optics or light, the days of using diffraction gratings or electroscopes is gone and these days students and teachers expect to be able to digitally capture and analyze spectra for light sources. Check out the video below showcasing a digital spectrometer used to analyze sources of light such as emission spectra from gases.
If you are a teacher or student interested in analyzing element spectra (e.g. Hydrogen), Electro-Technic Products has several spectrum tubes filled with research grade gases and associated power supplies that can be used along with digital spectrometers to create an ideal learning experience!
