Large Role In Heisenbergs Uncertainty Principle
1,641 wordsWerner Heisenberg One cannot fully appreciate the work of Werner Heisenberg unless one examines his contributions in the context of the time in which he lived. Werner Karl Heisenberg was born in Wuerzburg, Germany, on December 5, 1901, and grew up in academic surroundings, in a household devoted to the humanities. His father was a professor at the University of Munich and undoubtedly greatly influenced young Werner, who was a student at the Maximilian Gymnasium. Heisenberg had the opportunity to...
Kinetic Energy Of The Electron
1,528 wordsIntroduction The Quantum Theory was the second of two theories which drastically changed the way we look at our physical world today, the first being Einstein " theory of Relativity. Although both theories revolutionized the world of physics, the Quantum Theory required a period of over three decades to develop, while the Special Theory of Relativity was created in a single year. The development of the Quantum Theory began in 1887 when a German physicist, Heinrich Hertz, was testing Maxwell's Th...
Frequency F Of The Incoming Light
1,715 wordsThe Photoelectric Effect The purpose of this experiment is to determine h / e (Plank's constant in units of electron volts), the work function F, and the threshold frequency for the photochathode surface provided. Three filters each having a distinct wavelength, were used to carry out this experiment. Utilizing these filters, 435.8 nm, 546.0 nm, and 577.0 nm, data in voltage and current was collected, as potential was selected at random points for each wavelength. This data was then plotted (cur...
Weight Theories Of The Atom
588 wordsThe notion of the atom all stared about 450 BC when a Greek scholar starting think when can something break on more, when are the pieces at their smallest, this mans name was Leucippus. Leucippus also had pupil who also thought the same way as Leucippus, his name was Democritus. They developed there ideas and when Democritus died his theory summed up briefly was that everything in the world was made of tiny pieced that could not be broken up any more. That how the word atom was derived from the ...
Electrons Move Around The Circular Path
591 wordsYou have already seen Rutherford Atomic model which was proposed by Ernest Rutherford in the year 1911 and I have told such facts about that model which was not reality encouraged. if it is seen in reality then among the atomic model Rutherford Atomic model was the 1st atomic model which was scientifically (doubt) organized & which in facts (doubt) a lot of conclusions about the atom which was not available there prior in (doubt). In this atomic model Rutherford never came to know what the reali...
694 wordsThe renowned physicist and Nobel Prize recipient Niels Henrik David Bohr, is known primarily for his pioneering work in the field of atomic theory. Bohr was born on October 7, 1885 in Copenhagen, Denmark and grew up in an intellectual atmosphere, being that his father was an eminent physiologist. During his childhood, Bohr demonstrated a fondness for understanding how things worked, and often repaired any instrument he could find. He excelled in his studies and was accepted at the University of ...
Energy Of Electrons
1,172 wordsDevelopment of Quantum Theory - Historical Perspective Quantum theory, the modern physical theory concerned with the emission and absorption of energy by matter and with the motion of material particles, is one of the most important theories devised in the 20th century. The theory is revolutionary as it replaces classical physics in the description of events at the microscopic level and now the theory provides the foundation for modern physics and chemistry. The person who formed the basis of th...
Electrical Resistance Below Their Critical Temperatures
432 wordsweb. The BCS theory (after is proponents US physicists John Bardeen, Leon Cooper and John Schrieffer) explains superconductivity in terms of electron pairs and packets of sound waves related to lattice vibrations (called phonons)... At temperatures below the critical temperature for particular metals (or metal alloys), the movement of electrons is enhanced by lattice vibrations (phonons) which cause electric field effects resulting in electron pairing (by overcoming what would normally be strong...
Energy Levels Of Electrons Outside The Nucleus
948 wordsIn the beginning of the 1800's John Dalton, an English scientist did work some work on gases, which lead him to the creation of a complex system of symbols for all known elements at the time. He took all the information he had collected, along with the Laws of Conservation of Mass, Definite Composition and Multiple Proportions and updated Aristotle's theory of matter with the Atomic Theory of Matter, which stated: – All matter is composed of tiny, indivisible particles called atoms. –...
