In Phenomena like Interference, diffrection etc wave nature is exhibited. CBSE Class 11 Physics Syllabus 2017 - 2018. 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. To overcome attraction forces on electrons, the photons of incident light must possess a certain minimum energy so as to release an electron from the metal surface. In photo electric effect, compton effect etc particle nature is observed. Moreover, the chapter covers various topics that explain a lot of things about the properties, effects, emission, and nature of radiation and matter. The photoelectric effect could be explained considering that radiations consist of small packets of energy called quanta. 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. Towards the end of the nineteenth century, Maxwell's equations established that light was an electromagnetic wave. Lectures by Walter Lewin. Dual Nature of Radiation and Matter: Wave theory of electromagnetic radiations explained the phenomenon of interference, diffraction and polarization. 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.

But as soon as it is irradiated with even less intense yellow light having frequency of 5.1×1014 to 5.2×1014 Hertz, photoelectrons are ejected. As the threshold frequency for potassium metal is 5.0. Dual Nature of Radiation and Matter Class 12 Notes Chapter 11. While photoelectric effect and Compton effect involve energy and momentum transfer, radiation behaves as if it is made of a bunch of particles-photons show particle nature of a wave. We will study the different nature that a matter possesses or exhibits and it can be either particle nature or wave nature. Chemistry Notes For Class 11 STRUCTURE OF ATOM Download In Pdf ☞ Class 12 Solved Question paper 2020 ☞ Class 10 Solved Question paper 2020. These packets of energy can be treated as particles. • There are four types of electron emission, namely, Thermionic Emission, Photoelectric Emission, Field Emission and secondary emission. CBSE Class 11 Chemistry Atomic Structure– Get here the Notes for CBSE Class 11 Chemistry Atomic Structure. 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. DUAL NATURE OF RADIATION AND MATTER 3. Electrons should have momentum as well as wavelength, just as photon has momentum as well as wavelength. Important topics of 12th Physics are covered. Lecture 2 . On the other hand, quantum theory of e.m. radiations successfully explained the photoelectric effect, Compton effect, black body radiations, X- ray spectra, etc. These rays are produced in a discharge tube at a pressure below 0.01 rom of mercury. Ex: When more and less intense yellow light is made to shine on potassium metal separately, then relatively more number of electrons will be ejected from the potassium metal irradiated with high intense yellow light. Where, m is the mass of the particle and v is its velocity.

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. Properties of Electromagnetic Radiation. Some properties of electromagnetic radiation, such as its refraction when it passes from one medium to another are explained best by describing light as a wave.

Maybe these were the questions that led Louis Victor de Broglie to come up with one of the most revolutionary equations in Physics, the de Broglie equation. Electrons should have momentum as well as wavelength, just as photon has momentum as well as wavelength.

Wave–particle duality postulates that all particles exhibit both wave and particle properties. How could we measure and prove that? Where, m is the mass of the particle and v is its velocity. These packets of energy can be treated as particles. m = mass of electron, E = total energy of electron.

The wave nature of light can be observed in the phenomena of interference, diffraction and polarisation. BNAT; Classes. YOGESH PANDEY CLASS XII CDAYAWATI MODI ACADEMY 2. This is a revolutionary concept of physics that tells that everything is a wave and particle. However, in the beginning of the twentieth century, scientists unravelled one of the best-kept secrets of nature - the wave particle duality.
