Seven Mirror Apparatus
notes: label: Description
content: Isaac Newton showed that when he passed white light through a glass prism, it was split into seven constituent colors; and by reversing the process, he could recombine these colored rays into white light. This simple apparatus with seven mirrors on a brass stand (one mirror is missing) demonstrates that phenomenon. This may have been made by Jules Duboscq in Paris.
