1705 - What is the theory proposed by Einstein to analyze the photoelectric effect?

The theory proposed by Einstein is called the "Photon Theory" or "Particle Theory." He said that light is made up of tiny particles called photons, not just waves. According to this theory, when light hits a metal surface, these photons can knock out electrons from the metal if they have enough energy. This explained the photoelectric effect, which is a phenomenon where light can cause electrons to be emitted from a material.
