WebFrench physicist Louis de Broglie won the Nobel Prize in 1929 for groundbreaking work in quantum mechanics. His work to show mathematically how subatomic particles share some of the same properties of waves was later proven correct through experiment. His particle wavelength equation is: λ = h/p. WebWhere λ is the wavelength, h is Planck’s constant, and m is the mass of a particle moving at a constant velocity. De Broglie proposed that particles can have wave-like properties. The de Broglie hypothesis was confirmed when matter waves were observed in George Paget Thomson’s cathode ray diffraction experiment and the Davisson-Germer experiment …
