Dear Readers, Compared to other sections, Chemistry is considered to be the most scoring section. (i) The radiant energy which is emitted or absorbed by the black body is not continuous but discontinuous in the form of small discrete packets of energy, each such packet of energy is called a 'quantum'. Planck’s radiation law, a mathematical relationship formulated in 1900 by German physicist Max Planck to explain the spectral-energy distribution of radiation emitted by a blackbody (a hypothetical body that completely absorbs all radiant energy falling upon it, reaches some equilibrium temperature, and then reemits that energy as quickly as it absorbs it). Can you explain this answer? Planck's Quantum Theory-a)The energy is radiated or absorbed by a body not continuously but discontinuously in form of small packets. All Rights Reserved. (i) The radiant energy which is emitted or absorbed by the black body is not continuous but discontinuous in the form of small discrete packets of energy, each such packet of energy is called a 'quantum'. Planck is considered the father of the Quantum Theory. When black body is heated, it emits thermal radiations of different wavelengths or frequency. Wave theory does not accurately explain photoelectric effect. Planck's Quantum Theory ,Structure of Atom - Get topics notes, Online test, Video lectures, Doubts and Solutions for CBSE Class 11-science on TopperLearning. What is black body radiation? These questions are very important in achieving your success in Exams after 12th. What wavelength of other photon? The Questions and Answers of The first use of quantum theory to explain the structure of atom was made by :a)Heisenbergb)Bohrc)Planckd)EinsteinCorrect answer is option 'B'. Max Planck … He was trying to explain black body radiation, but could not explain with available theoretical tools at that time. This is explained with the help of Wien's displacement law, Planck's law and Stefan-Boltzmann law. Pravendra Tomar [ PT Sir ] IITJEE , NEET 3,920 views 12:26 Light of wavelength 1281.8nm is emitted when an electron of hydrogen atom drops from 5th to 3rd energy level calculate the wavelength of the photon emitted when electron falls from 3rd to ground level. Planck’s quantum theory is the fundamental theory of quantum mechanics. energy is quantized.

James Clerk Maxwell’s synthesis of electric, magnetic, and optical phenomena and the discovery by Heinrich Hertz of electromagnetic waves were theoretical and experimental triumphs of the first order. Planck’s radiation law, a mathematical relationship formulated in 1900 by German physicist Max Planck to explain the spectral-energy distribution of radiation emitted by a blackbody (a hypothetical body that completely absorbs all radiant energy falling upon it, reaches some equilibrium temperature, and then reemits that energy as quickly as it absorbs it). One photon of light carries exactly one quantum of energy. A-1, Acharya Nikatan, Mayur Vihar, Phase-1, Central Market, New Delhi-110091.
