Seven Mirror Apparatus

Usage conditions apply
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 in this example) demonstrates that phenomenon.
