Spectrometer and spectrum tubes

Have you ever wondered how astronomers know so much about distant galaxies when we have never even sent a probe to the sun. The answer is spectroscopy, and this allows you to explore different lights and what colours make them up.

Different lights produce light in different ways, and so produce very different spectra. With a spectroscope you can investigate the hidden depths of light.


We have built these as outreach kit and exhibits, with different light sources to look at including a variety of white light sources, a selection of gas discharge tubes and looking at fluorescent materials.
