In 1861, Gustav Kirchhoff published the astonishing results that he could, merely by examining the light received from the Sun, determine what elements it was made from. One this episode, we'll trace the scientific investigation of the nature of light from Isaac Newton through Joseph Fraunhofer to the work of Kirchhoff and Robert Bunsen.
