Mar 03, · How did Max Planck contribute to the atomic theory? Max Planck, a German physicist, is best known as the originator of the quantum theory of energy for which he was awarded the Nobel Prize in His work contributed significantly to the understanding of atomic and subatomic processes. What did Max Planck contribute to the atomic theory? Max Planck basic contribution: Max Planck is considered as one of the biggest theoretical physicist of all times.

He contributed to the Quantum Theory. You probably know that energy in the atom, but electrons jumping to higher levels or falling back is emitted in bundles called Quanta. The problems of radiation processes engaged his attention and he showed that these were to be considered as electromagnetic in nature.
From these studies he was led ma the problem of the distribution of energy in the spectrum of full radiation. Experimental observations on the what did max planck contribute to atomic theory distribution of the energy emitted by a black body as a function of temperature were at variance with the predictions of classical physics.
Planck was able to deduce the relationship between the wtomic and the frequency of radiation. In a paper published inhe announced his derivation of the relationship: this was based on the revolutionary planvk that the energy emitted by a resonator could only take on discrete values or quanta. The energy for a resonator of frequency v is hv where h is a universal constant, now called Planck's constant.
This was not only Planck's most important work but also marked a turning point in the history of physics. The importance of the discovery, with its far-reaching what is the purpose of a transistor in a circuit on classical physics, was not appreciated at first.
However the evidence for its validity gradually became overwhelming as its application accounted for many discrepancies between observed phenomena and classical theory. Among these applications and developments may be mentioned Einstein's explanation of the photoelectric effect. Planck's work on the Quantum Theory, as it came to be known, was published in the Annalen der Physik.

Planck made many contributions to theoretical physics, but his fame rests primarily on his role as originator of the quantum theory. This theory revolutionized our understanding of atomic and subatomic processes, just as Albert Einstein ’s theory of . Planck's biggest contribution to the atomic theory, and physics itself, was the creation of the Quantum theory. This theory said that energy was in waves and can only be emitted in certain "quanta" instead of being emitted in any value. This became the basis of almost all atomic findings after. Dec 09, · In , a scientist named Max Planck made a discovery that would change science forever and have a profound impact on our understanding of both light and atomic structure. In this lesson, learn.
He entered the University of Munich in the fall of and spent a year at the University of Berlin — He received his doctoral degree in July at the unusually young age of This work laid the foundation for quantum theory , which won him the Nobel Prize for Physics in Max Planck made many contributions to theoretical physics , but his fame rests primarily on his role as an originator of quantum theory.
This theory revolutionized our understanding of atomic and subatomic processes. Planck made many contributions to theoretical physics , but his fame rests primarily on his role as originator of the quantum theory. Together they constitute the fundamental theories of 20th-century physics. Both have forced humankind to revise some of the most-cherished philosophical beliefs, and both have led to industrial and military applications that affect every aspect of modern life.
Max Karl Ernst Ludwig Planck was the sixth child of a distinguished jurist and professor of law at the University of Kiel. But Planck excelled in all subjects, and after graduation at age 17 he faced a difficult career decision.
He ultimately chose physics over classical philology or music because he had dispassionately reached the conclusion that it was in physics that his greatest originality lay. Music, nonetheless, remained an integral part of his life. He possessed the gift of absolute pitch and was an excellent pianist who daily found serenity and delight at the keyboard, enjoying especially the works of Schubert and Brahms. He also loved the outdoors, taking long walks each day and hiking and climbing in the mountains on vacations, even in advanced old age.
Planck entered the University of Munich in the fall of but found little encouragement there from physics professor Philipp von Jolly. During a year spent at the University of Berlin —78 , he was unimpressed by the lectures of Hermann von Helmholtz and Gustav Robert Kirchhoff , despite their eminence as research scientists.
The following year he completed his Habilitationsschrift qualifying dissertation at Munich and became a Privatdozent lecturer.
In , after the death of Kirchhoff, Planck received an appointment to the University of Berlin, where he came to venerate Helmholtz as a mentor and colleague. In he was promoted to ordentlicher Professor full professor. He had only nine doctoral students altogether, but his Berlin lectures on all branches of theoretical physics went through many editions and exerted great influence.
He remained in Berlin for the rest of his active life. The first instance of an absolute in nature that impressed Planck deeply, even as a Gymnasium student, was the law of the conservation of energy , the first law of thermodynamics.
Later, during his university years, he became equally convinced that the entropy law , the second law of thermodynamics , was also an absolute law of nature. In —60 Kirchhoff had defined a blackbody as an object that reemits all of the radiant energy incident upon it; i.
There was, therefore, something absolute about blackbody radiation, and by the s various experimental and theoretical attempts had been made to determine its spectral energy distribution—the curve displaying how much radiant energy is emitted at different frequencies for a given temperature of the blackbody. Planck learned of these results just before a meeting of the German Physical Society on October He also saw what this dependence had to be in the low-frequency region in order to reproduce the experimental results there.
Planck guessed, therefore, that he should try to combine these two expressions in the simplest way possible, and to transform the result into a formula relating the energy of the radiation to its frequency. That was the task to which Planck immediately directed his energies, and by December 14, , he had succeeded—but at great cost.
To achieve his goal, Planck found that he had to relinquish one of his own most cherished beliefs, that the second law of thermodynamics was an absolute law of nature. He adduced additional evidence for the importance of his formula by using it to evaluate the constant h his value was 6. A profound revolution in physical theory was in the making. He was driven to introduce it strictly by the force of his logic; he was, as one historian put it, a reluctant revolutionary.
In Einstein introduced the wave-particle duality into physics. In October Planck and Einstein were among the group of prominent physicists who attended the first Solvay conference in Brussels.
In Niels Bohr also contributed greatly to its establishment through his quantum theory of the hydrogen atom. Ironically, Planck himself was one of the last to struggle for a return to classical theory, a stance he later regarded not with regret but as a means by which he had thoroughly convinced himself of the necessity of the quantum theory.
