Photoelectric Effect The phenomenon of emission of photoelectron from the surface of metal, when a light beam of suitable frequency is incident on it, is called photoelectric effect. Dual Behavior of Electromagnetic Radiation: ... Go back to Class 11 Main Page using below links Class 11 Maths Class 11 Physics Class 11 Chemistry Class 11 Biology. Lectures by Walter Lewin. Towards the end of the nineteenth century, Maxwell's equations established that light was an electromagnetic wave. A central concept of quantum mechanics, this duality addresses the inability of classical concepts like "particle" and "wave" to fully describe the behavior of quantum-scale … STRUCTURE OF ATOM Class 11 Chemistry CBSE Board Free download Aoms: Atom is the smallest indivisible particle of the matter. Einstein explained photoelectric effect using Planck's quantum theory of electromagnetic radiation. matter shows both particle and wave nature. Dual Behaviour of Electromagnetic Radiation. If the energy possessed by the photon is high then the energy transferred to the electron is also high and that makes high kinetic energy of the ejected electron. A central concept of quantum mechanics, this duality addresses the inability of classical concepts like "particle" and "wave" to fully describe the behavior of quantum-scale … What if other quantities had dual nature? 1. Atom is made of electron, proton and neutrons. Dual Nature of Radiation and Matter (chapter 11) Cathode Rays Cathode rays are the stream of fast moving electrons. When these electromagnetic radiations are arranged in order to their increasing wavelengths or decreasing frequencies, the complete spectrum obtained is called electromagnetic spectrum. Properties of Cathode Rays (i) Cathode rays are not electromagnetic rays. whenever radiation interacts with matter, it displays particle like properties (Black body radiation and photoelectric effect). where. de Broglie’s relation is Visit www.ncerthelp.com For All NCERT solutions, CBSE sample papers, Question papers, Notes for Class 6 to 12 Please Visit www.ncerthelp.com For Video lectures of all subjects Class 9 to 12 How could we measure and prove that? To assist you with that, we are here with notes. Lecture 3. Candidates who are ambitious to qualify the CBSE Class 11 Chemistry with good score can check this article for Notes. Electromagnetic radiation can be defined as a form of energy that is produced by the movement of electrically charged particles traveling through a matter or vacuum or by oscillating magnetic and electric disturbance. Dual behaviour of matter; Heisenberg uncertainty principle; Dual Behaviour of Matter The French physicist, de Broglie proposed that matter, like radiation, should also exhibit dual behaviour i. e., both particle and wavelike properties. So the orbit must be narrowed. The best app for CBSE students now provides Dual Nature of Radiation and Matter class 12 Notes latest chapter wise notes for quick preparation of CBSE board exams and school-based annual examinations. CBSE Class 11 Chemistry Atomic Structure– Get here the Notes for CBSE Class 11 Chemistry Atomic Structure. Electrons should have momentum as well as wavelength, just as photon has momentum as well as wavelength. On the other hand, radiations exhibit a phenomenon of interference and diffraction which indicated that they possess wave nature. This means that just as the photon, electrons should. In Phenomena like Interference, diffrection etc wave nature is exhibited. Chemistry Notes For Class 11 STRUCTURE OF ATOM Download In Pdf ☞ Class 12 Solved Question paper 2020 ☞ Class 10 Solved Question paper 2020. CBSE Class 12 Physics Chapter 11 Dual Nature of Radiation and Matter Notes in PDF are available for free download in myCBSEguide mobile app. Properties of Electromagnetic Radiation. An electromagnetic wave has dual (wave–particle) nature. The wave associated with the particle is called a matter wave or a de Broglie wave. One the one hand, it could explain the photoelectric effect satisfactorily but on the other hand, this was not consistent with the known wave behavior of light which could account for the phenomena of interference and diffraction.
