Photon Interference Pattern Diagram

This diagram visually represents a core concept in quantum mechanics: the wave-particle duality, specifically as seen in a photon interference experiment. It depicts a single photon, starting in red, which then seems to take multiple possible paths, shown in blue, before ultimately recombining. These paths lead to the formation of an interference pattern on a detector, symbolized by the grey vertical bar. It's a conceptual illustration of how a single photon can interfere with itself, demonstrating its wave-like nature.
