Brogliehullámhosszával

De Broglie wavelength refers to the wavelength of a matter wave, as proposed by Louis de Broglie. He hypothesized that all matter exhibits wave-like properties. The de Broglie wavelength of a particle is inversely proportional to its momentum. The formula for the de Broglie wavelength (λ) is given by λ = h/p, where h is Planck's constant and p is the momentum of the particle. Momentum (p) is calculated as the product of mass (m) and velocity (v), so the formula can also be written as λ = h/(mv).

This concept is fundamental to quantum mechanics and explains phenomena like electron diffraction. For macroscopic objects, the de Broglie wavelength is extremely small due to their large mass, making their wave-like nature practically unobservable. However, for microscopic particles like electrons, protons, and neutrons, the wavelength is significant enough to be detected and utilized in experiments. The Davisson-Germer experiment, which demonstrated electron diffraction by a crystal lattice, provided crucial experimental evidence supporting de Broglie's hypothesis. Understanding the de Broglie wavelength is essential for comprehending the quantum behavior of matter.
