Today (March 19, 1987) is the Memorial Day of Louis de Broglie won the Nobel Prize in Physics for his discovery of the wave nature of electrons on the dual properties of particles.
Louis de Broglie was born on
August 15, 1892, in France. Sean-Maritime, the youngest son of Victor of Broglie,
was born into a noble family in Dieppe. De Broglie aimed for a career in
humanity and received his first degree in history. He then turned his attention
to mathematics and physics and graduated with a degree in physics. After the
outbreak of World War I in 1914, he provided his services to the military in
the development of radio communications.
In physics and
chemistry, wave-particle duality or wave-particle duality is the concept that
all matter (i.e., all the electrons in the material) are wave-like and
particle-like. This is the central concept of quantum mechanics, which seeks to
explain the behaviour of objects that cannot be fully explained by the concepts
of wave and particle. Various interpretations of the quantum mechanism seek to
clarify this paradoxical origin.
The concept of duality was formed
in the 1600s based on the debates when Christian Huygens
and Isaac Newton proposed two opposing principles on light and matter. As a
result of the research of Albert Einstein and Louis Broglie, modern scientific
principles accept that all matter has both wave and particle properties. These
phenomena are known to apply not only to elementary particles but also to
composite particles such as atoms and molecules.
For his doctorate in 1924, Louis
de Broglie studied the wave nature of electrons. De Broglie first outlined his
concept of the dual nature of wave-particles at the French Academy of
Hypotheses. Not only light, but all matter is wave-like in nature. (λ = h / p;
p - momentum, h - constant for plank)
Matter waves are also called
procrastination waves and their wavelength is called the D-Broglie wavelength.
This is the first step in the wave theory of objects. He was awarded the Nobel
Prize in Physics in 1929 for his theory of De Broglie. In 1952 he was awarded
the Kalinga Award. De Broglie passed away on March 19, 1987, at the age of 94 in
Lausanne.
