These questions are very important in achieving your success in Exams after 12th. The failure of the classical electromagnetic theory of radiation to explain the phenomenon of photoelectric effect led Max Planck (1 901) to propose a new theory known as Quantum theory of radiation. rosesharma rosesharma 01.09.2019 Chemistry Secondary School Explain Planck's Quantum theory? When a black body is heated, it emits thermal radiations of different wavelengths or frequency. According to electromagnetic wave theory, energy is emitted or absorbed discontinuously, i.e., in certain definite packets called 'Quanta' whereas according to Planck's quantum theory, the energy is emitted or absorbed continuously The main points of quantum theory are : (i) Substances radiate or absorb energy discontinuously in the form of small packets or bundles of energy. Present quantum field theory explains classical electromagnetic radiation as emergent from zillions of photons, as can be seen here . theories must fit: quantum mechanics.

As progress in the science field was happening, Maxwell’s suggestion about the wave nature of electromagnetic radiation was helpful in explaining the phenomena such as interference, diffraction etc. See Answer. NCERT Solutions. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. Planck further assumed that when an oscillator changes from a state of energy E 1 to a state of lower energy E 2, the discrete amount of energy E 1 − E 2, or quantum of radiation, is equal to the product of the frequency of the radiation, symbolized by the Greek letter ν and a constant h, now called Planck’s constant, that he determined from blackbody radiation data; i.e., E 1 − E 2 = hν. 1.

Dear Readers, Compared to other sections, Chemistry is considered to be the most scoring section. The main points of this theory are : 1)The radiant energy is emitted or absorbed not continuously but discontinuously in the form of small discrete packets of energy.Each such packet of energy is called quantum. The word "quantum" refers to the fact that light is apparently released and absorbed in lumps or quanta. Physics. 1. Subscribe our channel now and never miss out on our latest videos for IIT JEE preparations! Biology . Quantum uncertainty Max Planck is widely credited for being the first person to realize that the energy of a body is “quantized”, but history shows that this is probably not what he had in mind at the time. It wasn't until Einstein and others used quantum theory for even further advancements in physics that the revolutionary nature of his discovery was realized. ON THE QUANTUM THEORY OF RADIATION A. EINSTEIN The formal similarity between the chromatic distribution curve for thermal radiation and the Maxwell velocity-distribution law is too striking to have remained hidden for long. So, it has applications in all those fields where quantum mechanics is being used. But this is not the main point of quantum theory. Improve this answer. Explain Planck's Quantum theory? Max Karl Ernst Ludwig Planck, ForMemRS (German: [maks ˈplaŋk] (); English: / ˈ p l æ ŋ k /; 23 April 1858 – 4 October 1947) was a German theoretical physicist whose discovery of energy quanta won him the Nobel Prize in Physics in 1918..

Max Planck in 1900, put forward a theory known after his name as Planck’s Quantum theory. Planck’s Quantum Theory. NCERT P Bahadur IIT-JEE Previous Year Narendra Awasthi MS Chauhan. In 1900, Planck made the assumption that … Quantum theory was developed during the first part of the last century by studying the behaviour of small things like atoms and photons (particles of light). To a greater or lesser extent all natural phenomena appear to be governed by the principles of quantum mechanics, so much so that this theory constitutes what is undoubtedly the most successful theory of modern physics. Quantum theory is a theory of matter; or more precisely it is a theory of the small components that comprise familiar matter. 2013-04-12 12:50:37. Indeed, the “discovery” of quantum theory should not be seen as a moment of insight in December 1900, but as an extended process by many physicists. Theory of the scattering of X-rsys and 7-11th by light elements. The main points of quantum theory are. Top Answer. ... one can point to Einstein and de Broglie as the main moves in this direction. (Albert Einstein, on Quantum Theory, 1940) Even the Greeks had already conceived the atomistic nature of matter and the concept was raised to a high degree of probability by the scientists of the nineteenth century. Principle thinking led to major breakthroughs throughout the history of quantum theory, beginning with the old quantum theory and quantum mechanics, the first definitive quantum theory, which it remains within its proper (nonrelativistic) scope. When black body is heated, it emits thermal radiation?s of different wavelengths or frequency. ii) The smallest packet of energy is called quantum. NCERT Solutions for Class 12 Physics. Log in. What is the main difference between electromagnetic wave theory and planck's quantum theory ? This is the so-called "old quantum theory" developed by Bohr and Sommerfeld, in which particle trajectories exist but are hidden, but quantum laws constrain them based on their action. Ask your question. It has, the book also argues, been equally important in quantum field theory, which has been the frontier of quantum theory for quite a while now, and more recently, in quantum information theory, where principle thinking was given new prominence.
