Louis de Broglie

Louis de Broglie was a French physicist who proposed that particles, like electrons, have wave-like properties, a concept known as wave-particle duality. This idea revolutionized our understanding of atomic physics and quantum mechanics, suggesting that matter can exhibit characteristics of both particles and waves. De Broglie's theory laid the groundwork for the development of quantum mechanics, influencing how we understand atomic structures, ionization (removing electrons from atoms), and excitation (promoting electrons to higher energy levels). His work helps explain various phenomena in atomic physics and the behavior of subatomic particles.
