In performign this quantum theory, he greatly affected by the dualism properties of light theory. Before de Broglie, Einstein mentioned that the short wavelength of light can be observed as it consists of some particles.
Then, Louis de Broglie successfully discovered the dualism in the matter. After discovered the quantum theory, in Louis de Broglie received his first Nobel Prize for Physics.
Louis de Broglie developed his theory in In his hypothesis, he stated that electrons have the properties of particles and waves. He came up with this thought after the discovery of dualism in light previously. Light posses the dual properties as particle and wave. Louis de Broglie then believed that matter or electrons might act just like light.
He mentioned that electrons create the waves in certain orbital around the nucleus. He called this wave as standing wave. Standing wave has its own energy, frequency and wavelength. In his research, he tried to find out the wave properties of the matter to add the particle properties in that matter. Louis de Broglie stated that the standing waves produced by electrons has the relation with discrete wavelength.
At that time, de Broglie quantum theory gained great popularity and recognition from influential figure at that time, including Albert Einstein. Louis de Broglie quantum theory successfully explained some questions about the previous atomic model, especially about the electron movements. From the experiment before, we knew that electrons moved around the nucleus in the path called orbits. However, there were some restrictions to these electron movements and electron orbits.
Then, Luois de Broglie quantum theory was able to give the answer to this question at that time. The standing wave made by electrons during its movement is the cause of those restrictions.
This wave will interfere and cancels out which create such a restriction in electron motions and orbitals. Louis de Broglie quantum theory gave such a strong impact to the atomic theory and chemistry in general. This theory also greatly contributed in the physics study, especially in the quantum physics study. Previously, there were some popular atomic theories conducted at that time. Another great example is that of Marie Curie. Incredibly, Louis de Broglie, with his first great scientific research, succeeded in laying one of the pillars of quantum physics: the wave—particle duality, which states that waves can behave like particles and vice versa.
And admitting the wave properties of electrons was the basis for inventing the electron microscope released in , which allows us to see things much smaller than typical optical microscopes permit, because the wavelength of the electron is much shorter than that of photons of visible light. In addition, he was the first world-renowned scientist who called for countries to join forces to meet the great challenges of science in multinational laboratories. CERN the European Organization for Nuclear Research was born of this request, and his long life he passed away at age 94 allowed him to see the exceptional achievements of this particle physics laboratory inspired by his scientific vision.
