Double-Slit Experiment Model

This model depicts Thomas Young's double-slit experiment from 1801, proving that light also behaves as a wave. The theory surrounding this experiment predicted that, if light is a wave, it should show both constructive and destructive interference when passing through a double slit. Contact with the slit creates a new starting point for a propagating wave (shown by the concentric circles and their origins). These new waves interact with each other both constructively and destructively, creating a repeating series of progressively dimming lines on the far wall starting at the center. I have added the waveform on the far wall that mathematically describes the dimming lines that would appear (roughly a sync function, but not exactly). This model can also be stood up as a Christmas Tree for a perfect Christmas decoration for science lovers!

Add some glue to the square posts protruding from the base (the part with the words) to make sure that the light bulb and the far wall are stuck securely in place.
