Consider this snippet from the history of physics. In the nineteenth century a scientific experiment was developed by Thomas Young, which seemed to prove that light is a wave-like phenomenon. In his Double Slit Experiment Young allowed light to enter through an open hole on one screen to shine onto a second screen with two slits. Beyond the second screen was a wall. When one slit was covered up, the light entered and the illumination on the wall was predictable. But when both slits were open the pattern of the light projection clearly showed a series of light and dark bands. The only rational explanation for these bands was wave interference. Thus light must be made up of waves. So far so good!
