$De Broglie's Matter Waves (1924) BACKGROUND In 1924, Louis de Broglie proposed a revolutionary idea: If light (a wave) can behave like a particle then particles like electrons can also behave like waves This concept introduced the idea of wave-_particle duality Louis de Broglie for matter. CORE CONCEPT FORMULA Every moving particle h 1 = =mv has an associated IV wavelength called Electron the de Broglie 1 = wavelensth wavelength h = Plancks constant p = momentum (mv) KEY TAKEAWAY Nucleus Smaller mass (Protons Neutrons) h 1 = Larger wavelength =mv Hisher velocity:- mv Smaller wavelength Smaller mass h 1= Larger wavelength mv EXPERIMENTAL PROOF Higher velocity Experimentally confrmed in KEY TAKEAWAY Smaller wavelength 1927 by Clinton Davisson Matter has dual nature: & Lester Germer: Particles can behave EXPERIMENTAL PROOF Davisson Germer experiment like waves Experimentally confirmed in showed electron diffraction; 1927 by Clinton Davisson proving that electrons & Lester Germer: behave like waves; E-[HEMISTRY HUB De Broglie's Matter Waves (1924) BACKGROUND In 1924, Louis de Broglie proposed a revolutionary idea: If light (a wave) can behave like a particle then particles like electrons can also behave like waves This concept introduced the idea of wave-_particle duality Louis de Broglie for matter.
