# How did Louis de Broglie contributions about electron probabilities contribute to modern atomic theory?

## How did Louis de Broglie contributions about electron probabilities contribute to modern atomic theory?

In 1924 Louis de Broglie introduced the idea that particles, such as electrons, could be described not only as particles but also as waves. This was substantiated by the way streams of electrons were reflected against crystals and spread through thin metal foils.

### What experiment did Louis de Broglie contribute to the atomic theory?

In this thesis (1924) de Broglie developed his revolutionary theory of electron waves, which he had published earlier in scientific journals. (See de Broglie wave.) The notion that matter on the atomic scale might have the properties of a wave was rooted in a proposal Einstein had made 20 years before.

**What does De Broglie relationship suggest?**

De Broglie proposed that as light exhibits both wave-like and particle-like properties, matter to exhibit wave-like and particle-like properties. This nature was described as dual behaviour of matter.

**Which of the following contribution did Louis de Broglie do for the electronic structure of matter?**

Louis de Broglie (In full:Louis-Victor-Pierre-Raymond, 7th duc de Broglie) was an eminent French physicist. He gained worldwide acclaim for his groundbreaking work on quantum theory. In his 1924 thesis, he discovered the wave nature of electrons and suggested that all matter have wave properties.

## Was Louis Broglie married?

He inspired the formation of the International Academy of Quantum Molecular Science and was an early member. His funeral was held 23 March 1987 at the Church of Saint-Pierre-de-Neuilly. Louis never married. When he died in Louveciennes, he was succeeded as duke by a distant cousin, Victor-François, 8th duc de Broglie.

### What was Werner Heisenberg’s major contribution to the modern atomic theory?

Werner Heisenberg contributed to atomic theory through formulating quantum mechanics in terms of matrices and in discovering the uncertainty principle, which states that a particle’s position and momentum cannot both be known exactly.

**What did Neil Bohr contribute to the atomic theory?**

In 1913, Niels Bohr proposed a theory for the hydrogen atom, based on quantum theory that some physical quantities only take discrete values. Electrons move around a nucleus, but only in prescribed orbits, and If electrons jump to a lower-energy orbit, the difference is sent out as radiation.

**What relationship did de Broglie use to come up with his expression for the wavelength of a particle?**

Because real particles do not travel at the speed of light, De Broglie submitted velocity (v) for the speed of light (c). Through the equation λ, de Broglie substituted v/λ for ν and arrived at the final expression that relates wavelength and particle with speed.

## What is the relation between de Broglie wavelength and kinetic energy?

De-Broglie wavelength of a particle is inversely proportional to the momentum of that particular body. We should know that kinetic energy and momentum of a particle is related as K. E=P22m.

### Who proposed the dualistic nature of light and extended the idea to electrons?

Prince Louis-Victor de Broglie

The dual nature of light has been extended to a similar duality in matter as well. Electrons and atoms were originally considered as corpuscles. In 1929 Prince Louis-Victor de Broglie was awarded the Nobel Prize for Physics for “his discovery of the wave nature of electrons”.

**When was Louis de Broglie died?**

March 19, 1987

Louis de Broglie/Date of death

English translation: The Current Interpretation of Wave Mechanics: A Critical Study, Elsevier, Amsterdam, 1964. Louis de Broglie died on March 19, 1987.

**What did Louis Victor de Broglie do?**

Louis Victor de Broglie, a theoretical physicist and member of the French nobility, is best known as the father of wave mechanics, a far-reaching achievement that significantly changed modern physics. For this groundbreaking work, de Broglie was awarded the 1929 Nobel Prize for physics.

## Who were Louis de Broglie’s parents?

Louis de Broglie’s father was Victor, Duc de Broglie, and his mother was Pauline d’Armaillé. Louis studied at the Lycée Janson de Sailly in Paris completing his secondary school education in 1909. At this stage he did not envisage a career in science, but was interested in taking literary studies at university.

### What is de Broglie’s theory?

De Broglie’s doctoral thesis Recherches sur la théorie des quanta Ⓣ of 1924 put forward this theory of electron waves, based on the work of Einstein and Planck. It proposed the theory for which he is best known, namely the particle-wave duality theory that matter has the properties of both particles and waves.
