   Was light a wave or a particle after the double slit experiment?

   • When Thomas Young performed the double-slit experiment in 1801, a beam of light produced a wave interference pattern, and physicists largely concluded that light was a wave and not a particle. Although most scientists had concluded that light was a wave and not a particle after the double-slit experiment, the story was not yet over.

   What happens when light is observed as a wave?

   • When light is observed as a wave, it can create interference patterns, such as those seen in the double-slit experiment. This wave behavior is evident when light propagates through space and interacts with obstacles like slits or gratings. On the other hand, light also behaves as a particle, composed of discrete units called photons.

   The double-slit experiment not only demonstrates the wave nature of light but also reveals the wave-particle duality when individual photons are used. Even when photons pass through the slits one at a time, they still produce an interference pattern, suggesting that each photon behaves like a wave passing through both slits simultaneously.
