De Broglie’s <strong>Wave</strong>-Particle Duality Principles<br />

• In 1924. de Broglie postulated the existence <strong>of</strong> matter waves. He suggested<br />

that since waves exhibit particle-like behavior, then particles should also be<br />

expected to show wave-like properties.<br />

• The hypothesis <strong>of</strong> de Broglie was the existence <strong>of</strong> a wave-particle duality<br />

principle. The momentum <strong>of</strong> a photon is given by<br />

• Then, de Broglie hypothesized that the wavelength <strong>of</strong> a particle can be<br />

expressed as (de Broglie wavelength <strong>of</strong> the matter wave).
