materiebølgen
Materiebølgen, also known as the de Broglie hypothesis, is a foundational concept in quantum mechanics. Louis de Broglie proposed in 1924 that all matter exhibits wave-like properties. This means that not only light, which was already known to behave as both a wave and a particle, but also particles like electrons, protons, and even larger objects, possess a wavelength. The wavelength of a particle is inversely proportional to its momentum, a relationship expressed by the equation λ = h/p, where λ is the de Broglie wavelength, h is Planck's constant, and p is the momentum of the particle.
This hypothesis was a radical departure from classical physics, which treated matter as purely particulate. The
