Early in his career, he asked the question that "if photons are light particles and also move as waves like all light does, then why don't other particles, such as electrons, also follow wave patterns?" He proposed that they must also move in wave motions. His revolutionary idea fueled his desire to better understand the behavior of particles and waves. This led to his discovery of matter waves, wave-particle duality and the de Broglie wave. The scientific community celebrated his findings and awarded Louis de Broglie the 1929 Nobel Prize for physics.
