Photoelectric effect light as a particle
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. Weblight is both wavelike and particle-like. This is known as wave-particle duality. Figure 8.3 Photons with low frequencies do not have enough energy to cause electrons to be ejected via the photoelectric effect. For any frequency of light above the threshold frequency, the kinetic energy of
