Light exhibits particle characteristics under certain conditions, primarily through photons, as demonstrated by the Compton effect. Both everyday light and high-energy electromagnetic waves like gamma rays and x-rays are forms of electromagnetic waves, composed of photons. The discussion highlights that while these waves differ in frequency, they share the fundamental property of being made up of particles. Additionally, the de Broglie hypothesis suggests that particles with mass can also exhibit wave properties. This interplay between wave and particle characteristics is a key aspect of quantum mechanics.
