6.5 De Broglie's Matter Waves
Compton's formula established that an electromagnetic wave can behave like a particle of light when interacting with matter. In 1924, Louis de Broglie proposed a new speculative hypothesis that electrons and other particles of matter can behave like waves. Today, this idea is known as de Broglie's hypothesis of matter waves.In 1926, De Broglie's hypothesis, together with Bohr's early ...
Matter wave
Matter waves are a central part of the theory of quantum mechanics, being half of wave-particle duality.At all scales where measurements have been practical, matter exhibits wave-like behavior.For example, a beam of electrons can be diffracted just like a beam of light or a water wave.. The concept that matter behaves like a wave was proposed by French physicist Louis de Broglie (/ d ə ˈ b ...

De Broglie Wavelength Hypothesis Overview
The De Broglie hypothesis proposes that all matter exhibits wave-like properties and relates the observed wavelength of matter to its momentum. After Albert Einstein's photon theory became accepted, the question became whether this was true only for light or whether material objects also exhibited wave-like behavior. Here is how the De Broglie hypothesis was developed.
de Broglie Wavelength: Definition, Hypothesis, and Equation
A fundamental equation core to de Broglie hypothesis establishes the relationship between a particle's wavelength and momentum.This equation is the cornerstone of quantum mechanics and sheds light on the wave-particle duality of matter. It revolutionizes our understanding of the behavior of particles at the quantum level.
De Broglie Hypothesis
De Broglie successfully provided the explanation to Bohr's assumption by his hypothesis. Today we know that every particle exhibits both matter and wave nature. This is called wave-particle duality. The concept that matter behaves like wave is called the de Broglie hypothesis, named after Louis de Broglie, who proposed it in 1924.

matter particles or objects is typically much larger than that carried by radiation, so even sub-atomic distances are much larger than the de Broglie wavelength and do not give rise to di raction.

DeBroglie: Wave Characteristics of Matter
Louis de Broglie extended the notion of wave motion from light to other particles, such as electrons. It is possible to calculate a de Broglie wavelength for anything, including an elephant! Explanation: The formula is λ = h p where h is Planck's constant, 6.63 ×10−34 m2kgs−1, and p is the momentum ( p = mv, mass times velocity).

3.3 Describing a Wave -- Part 1: The de Broglie Wave Velocity We can easily calculate a velocity for de Broglie waves. Beiser calls it "v p," and later shows that vp is the phase velocity of the waves. A wave velocity is given by vp=f . De Broglie postulated that =h/mv for particles as well as waves.
Wave Nature of Matter and De Broglie's Equation
Heisenberg's Uncertainty. The Davisson-Germer experiment proved beyond doubt the wave nature of matter by diffracting electrons through a crystal. In 1929, de Broglie was awarded the Nobel Prize for his matter wave theory and for opening up a whole new field of Quantum Physics. The matter-wave theory was gracefully incorporated by Heisenberg ...

Key Notes On Broglie's Hypothesis Of Matter Wave
Broglie's hypothesis of matter waves has some pretty far-reaching implications. It suggests that, at a microscopic level, all Matter is in a constant state of vibration and flux. It also means that the very act of observation affects the behaviour of particles. It has enormous implications for our understanding of the universe and how we view ...
What are Matter Waves?
Matter waves, also known as de Broglie waves, are defined as the wave-like behavior exhibited by particles at the quantum scale. According to de Broglie's hypothesis, any moving particle or object has an associated wave whose wavelength is inversely proportional to the momentum of the particle [ 1 ]. This relationship is expressed by the ...
de Broglie Wavelength
The de Broglie wavelength is inversely proportional to momentum. Hence, the de Broglie wavelengths of the α-particle and residual nucleus will be in the ratio = 1:1. Question 11: The operation of the electron microscope depends on the: (a) Very short wavelength of X-rays (b) Wave nature of electrons (c) Electromagnetic theory of waves
de Broglie hypothesis for matter waves in quantum theory
The de Broglie hypothesis states that all matter particles behave like waves when they are in motion. It can be observed at microscopic level only. It's difficult to observe the wave nature of macroscopic particles due to their heavy mass. Sometimes, this statement is called the definition of de Broglie hypothesis.
What is De Broglie Hypothesis?
De Broglie's Hypothesis says that Matter consists of both the particle nature as well as wave nature. De Broglie wavelength λ is given as λ = h p, where p represents the particle momentum and can be written as: λ = h m v. Where, h is the Planck's constant, m is the mass of the particle, and v is the velocity of the particle.

De Broglie referred to these waves associated with material particles as matter waves. The wavelength of the matter waves, given by equation (1), is now known as de Broglie wavelength and the equation is known as de Broglie relation. ... the same kinetic energy, and (c) the same momentum.

From 1948 until around 1965, Louis de Broglie, awarded the Nobel Prize for Physics in 1929 for his fundamental contributions to quantum theory, pursued a systematic study of the formal analogies between wave mechanics and the thermomechanics of Boltzmann and Helmholtz. As part of this line of research, he produced several interesting observations, which were, however, published only in French ...
Sound waves and fluctuations in one-dimensional supersolids
We examine the low-energy excitations of a dilute supersolid state of matter with a one-dimensional crystal structure. A hydrodynamic description is developed based on a Lagrangian, incorporating generalized elastic parameters derived from ground state calculations. The predictions of the hydrodynamic theory are validated against solutions of the Bogoliubov--de Gennes equations, by comparing ...
