Answer 1

In advanced quantum mechanics, Louis de Broglie systematically hypothesized the revolutionary concept of wave-particle duality. He rigorously proposed that just as electromagnetic radiation exhibits distinct particle-like behavior (photons), moving physical matter (like electrons, protons, and atoms) must conversely exhibit distinct wave-like behavior.

These specific probability waves physically associated directly with moving particles are termed 'matter waves'. Their absolute wavelength ( $λ$ ) is mathematically inversely proportional entirely to the particle's physical momentum ( $p = m v$ ), rigidly defined by the fundamental de Broglie equation:

λ = \frac{h}{p} = \frac{h}{m v}
