Who discovered the wave particle duality of light?
physicist Albert Einstein
On the basis of experimental evidence, German physicist Albert Einstein first showed (1905) that light, which had been considered a form of electromagnetic waves, must also be thought of as particle-like, localized in packets of discrete energy.

What is Louis de Broglie famous for?
Louis de Broglie, in full Louis-Victor-Pierre-Raymond, 7e duc de Broglie, (born August 15, 1892, Dieppe, France—died March 19, 1987, Louveciennes), French physicist best known for his research on quantum theory and for predicting the wave nature of electrons. He was awarded the 1929 Nobel Prize for Physics.
Who proposed the particle theory of light?
Isaac Newton
The most prominent advocate of a particle theory of light was Isaac Newton. Newton’s careful investigations into the properties of light in the 1660s led to his discovery that white light consists of a mixture of colours.
What is de Broglie wave-particle duality?
Broglie devised that all matter had properties of both waves and particles. By confirming the theory that particles could act as waves simultaneously, physicists had discovered that electron streams act the same way as light. …
Did Einstein discovered wave-particle duality?
Albert Einstein, who, in his search for a Unified Field Theory, did not accept wave–particle duality, wrote: This double nature of radiation (and of material corpuscles) has been interpreted by quantum-mechanics in an ingenious and amazingly successful fashion.
Was Louis Broglie married?
In 1901, he was married to Camille Bernou de Rochetaillée (1888–1966) in Paris. They had one daughter, Laure, born on 17 November 1904, who died, aged six, on 12 June 1911.
Where did Louis de Broglie go to school?
University of Paris
Louis de Broglie/Education
After the death of his father when de Broglie was fourteen, his eldest brother Maurice arranged for him to obtain his secondary education at the Lycée Janson de Sailly in Paris. After graduating from the Sorbonne in 1909 with baccalaureates in philosophy and mathematics, de Broglie entered the University of Paris.
How old was Louis de Broglie when he died?
94 years (1892–1987)
Louis de Broglie/Age at death
Louis de Broglie died on 19 March 1987, aged 94. His passing should incite us to’reflect upon what he has contributed to all physicists in the course of his long career, which was in many respects quite exceptional.
What is electromagnetic theory of light?
The electromagnetic theory of light was introduced by Maxwell in 1864. According to this theory, light waves are of the same character as the electromagnetic waves, that are caused by a rapidly osci11ating electric current. One of these two directions can be considered to be that of the electric field.
What did Einstein call the particles of light?
photon
The light particle conceived by Einstein is called a photon. The main point of his light quantum theory is the idea that light’s energy is related to its oscillation frequency (known as frequency in the case of radio waves).
