Louis de Broglie proposed a groundbreaking theory in 1924 called the wave-particle duality of matter. Before this, scientists believed that light behaved either as a particle (in the case of photons) or as a wave (like in electromagnetic radiation). De Broglie extended this idea to matter, specifically particles like electrons.
His theory suggested that particles of matter (such as electrons, protons, and even atoms) could also behave as waves. This idea was revolutionary because it contradicted the classical idea that matter is only made up of particles. De Broglie introduced the concept of matter waves, where he argued that just like light, particles could exhibit both wave-like and particle-like behavior depending on the situation.
He even came up with an equation to describe the wavelength of these matter waves, which is:
\[
\lambda = \frac{h}{p}
\]
Where:
This theory explained why electrons in atoms only occupy specific orbits (as these orbits correspond to standing waves) and helped lay the foundation for quantum mechanics.
In short, de Broglie showed that all matter can have wave-like properties, not just light, which was a key idea in the development of quantum physics.

Where:
- \( \lambda \) is the wavelength of the matter wave,
- \( h \) is Planck's constant (a very small number),
- \( p \) is the momentum of the particle (which is the mass of the particle multiplied by its velocity).
