Light exhibits both wave-like and particle-like behaviors, a phenomenon known as wave-particle duality. This idea was first proposed by Louis de Broglie in the 1920s and confirmed by experiments, such as the double-slit experiment. Light can act as a wave, exhibiting characteristics such as diffraction and interference, and as a particle, exhibiting quantized energy as photons. The dual nature of light is described by quantum mechanics and is a fundamental aspect of our understanding of the nature of light and matter.
