Come interpretare l’esperimento del disco di Newton?
In 1666 Newton decomposed white light with a prism to make so-called appear rainbow colors. He represented these colors on a disk, which we usually spin to make white appear. But it’s this experience that’s really symmetrical to that of the prism? We will see here, with the help of a spectrometer and a digital microscope, that while the prism experiment provides information on the nature of light and its spectral components, the disc experiment provides insight into how it works of our visual system.
