Afterwards, though, he turned his attention toward mathematics and physics and received a degree in physics. He was the youngest of three sons born to Victor de Broglie, a diplomat, and Pauline de La Forest d'Armaillé. Before him are Owen Willans Richardson, Ibn al-Haytham, Heinrich Hertz, Lawrence Bragg, Christiaan Huygens, and James Clerk Maxwell.

There were also loopholes in the new theory. His examiners and the members of the academic board were impressed but deeply skeptical. Only in these orbits would the electron waves be in phase (at a particular point in the frequency cycle) with themselves and not cancel themselves out by their own interference.

Doctorate and Early Career

In 1924, de Broglie submitted his work, "Recherches sur la théorie des quanta" ("Investigations on the Theory of Quanta"), as a doctoral dissertation to the Faculty of Sciences at the University of Paris.

Erwin Schrödinger took Einstein's advice and used de Broglie's ideas as the

It was known that as the intensity of the light increased, the number of electrons emitted from the surface also increased, but the speed of the electrons never exceeded a particular maximum. He inspired the formation of the International Academy of Quantum Molecular Science and was an early member.

Important theories

Matter and wave-particle duality

Main article: De Broglie hypothesis

"The fundamental idea of [my 1924 thesis] was the following: The fact that, following Einstein's introduction of photons in light waves, one knew that light contains particles which are concentrations of energy incorporated into the wave, suggests that all particles, like the electron, must be transported by a wave into which it is incorporated...

By the end of the 19th century, classical physics had achieved such great success that some scientists began to doubt whether any fundamental scientific problems remained to be solved. The wave-like behaviour of particlesdiscovered by de Broglie was used by Erwin Schrödinger in his formulation of wave mechanics.

Only in the last decades of the century had striking discoveries been made, such as X-rays, radioactivity, and the electron.

The Birth of Quantum Theory

In 1900, Max Planck proposed his revolutionary quantum theory to explain the relationship between the temperature of a body and the radiation it emits. UNESCO awarded him the first Kalinga Prize in 1952 for his work in popularizing scientific knowledge, and he was elected a Foreign Member of the Royal Society on 23 April 1953.

The position of each spectral line corresponds to the frequency of the particular component. He established a center for applied mechanics at the Henri Poincaré Institute, where research into optics, cybernetics, and atomic energy were carried out.

    However, on Einstein's urging, de Broglie was awarded his doctorate.

    The energy difference between the orbits, lost by the electron in the transition, is emitted as a quantum of energy, or photon – radiation with a frequency proportional to the energy difference. However, until the end of his life de Broglie returned to a direct and real physical interpretation of matter-waves, following the work of David Bohm.

    If the electron's speed changed, so would the orbit's position.
