WebBut the experiment based on the photoelectric effect stated that the photoelectric effect also consists of energy packets. The wave nature of light means that light can behave as an electromagnetic wave. On the other hand, the particle nature of light means the light comprising of. particles and it is known as photons. WebJan 11, 2024 · Photoelectric Effect and the Particle Nature of Light. In 1905, Albert Einstein (1879-1955) proposed that light be described as quanta of energy that behave as particles. A photon is a particle of electromagnetic radiation that has zero mass and carries a quantum of energy. The energy of photons of light is quantized according to the E=hv …
