Photon in Double Slit Beginning of controversy: First of all, two models are proposed based on observations: one states that light is made up of particles, and the other states that light is a wave. In the era of Isaac Newton, there was a great debate among the scientific community about the nature of light. Some believed that light is made up of particles and simply follows collision rules, similar to other particles when striking any object. On the other hand, some believed that it is a wave. Surprisingly, both communities are totally right because phenomena like the photoelectric effect and the Compton effect provide enough evidence that light has particle-like behavior. In contrast, phenomena like interference and diffraction prove that light is a wave, not a particle. This was the most famous controversy in the era of the 16th to 18th century. Many scientists came and gave their opinions on light. Newton also...
