Hunting for Spectra
With this making lab, you will discover some aspects of light, while building a real scientific instrument – namely, a spectroscope. This is a basic astronomical tool, which allows us to study the chemical composition and the physical state of the celestial objects we observe. Obviously, the spectroscope you will build is not exactly like those used by astronomers in order to observe the stars, but it does work well, and will enable you to break down the light of surrounding sources into a rainbow of colours.
