de Broglie wavelength

The de Broglie wavelength is a concept in quantum physics that describes how particles, like electrons, can behave like waves. According to Louis de Broglie, every moving particle has a wavelength related to its momentum—the more momentum it has, the shorter its wavelength. This wave-like nature becomes significant for tiny particles, influencing their behavior at atomic and subatomic scales. Think of it as particles having a "wave signature" that helps explain phenomena such as electron diffraction. In essence, the de Broglie wavelength bridges particles and waves, highlighting the duality fundamental to quantum mechanics.
