Answer
The Compton Effect, famously discovered by Arthur Compton, revolves around the interaction between photons and matter. This phenomenon, observed in 1923, demonstrated that photons, previously thought to be solely waves, also possess particle-like characteristics. Compton's groundbreaking discovery transformed our understanding of the nature of light and solidified the wave-particle duality principle, revolutionizing the field of quantum mechanics and earning him the Nobel Prize in Physics in 1927.
