Double Light Leak
In the double slit experiment, a controlled light source such as a laser is aimed at a screen with two vertical, parallel slits. Although the photons behave like particles when striking the first screen, colliding as points on the flat surface, the particles that pass through the open slits appear as varying bands of light and dark shadows, showing a more wave-like behavior. The experiment evidences the contrasting mannerisms of light, demonstrating the limitation of the observer’s ability to forecast the outcome of an observed phenomenon.
