I have a question. According to the video you posted, when the slit gets to a certain point, about 100th of an inch (cm?) wide, the laser beam as it exits the slit gets less determined (because of Uncertainty), and it begins to get wider and spreads out on the screen. Lewin’s explanation was”…that’s just the way the world works!” But why does it get wider and wider? How can this be? As the slit gets narrower, the beam should get narrower, too! Why?????????

The reason why is because the photon has more of a choice as the slit gets narrower and narrower.
