Who established the wave nature of particles?

Correct option is A

The correct answer is (a) De Broglie
Explanation:
· The wave nature of particles was proposed by Louis de Broglie in 1924.
· He introduced the concept of wave–particle duality, stating that particles like electrons exhibit both particle-like and wave-like properties.
· According to de Broglie, the wavelength of a moving particle is inversely proportional to its momentum. This relationship links matter with wave behavior and laid the foundation of quantum mechanics.
Information Booster:
• The wave nature of electrons was experimentally confirmed by Davisson and Germer (1927) through electron diffraction. • De Broglie was awarded the Nobel Prize in Physics in 1929 for his discovery. • This concept is fundamental to quantum mechanics and atomic structure theories. Wave–particle duality applies to both matter and radiation, forming a core principle of modern physics.
Additional Knowledge:
(b) Fermi – Enrico Fermi • Known for the first nuclear reactor (Chicago Pile-1). • Developed Fermi–Dirac statistics for particles called fermions.
(c) Pauli – Wolfgang Pauli • Proposed the Pauli Exclusion Principle, which explains electron arrangement in atoms.
(d) Clark Maxwell – James Clerk Maxwell • Formulated the classical electromagnetic theory, unifying electricity, magnetism, and light.
