## particle nature of electromagnetic radiation class 11 notes

4. Maxwell suggested that when an electrically charged particle moves under acceleration that time alternating electrical and magnetic fields are produced which helps the particle in propagation. We hope you enjoyed learning and were able to grasp the concepts. Wavelength and frequency of a wave are inversely proportional. Black Body Radiation The velocity of a wave is the product of multiplication of wavelength and frequency. Dual Nature of Radiation and Matter Class 12 Chapter 11 Notes 1. Video explain methods & techniques to solve numericals on particle nature of electromagnetic radiations ﻿helpful for CBSE 11 Chemistry Ch.2 structure of atom CBSE 11 Chemistry 01 … Matter waves-wave nature of particle, de Broglie relation. 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. Let’s start the introduction of “Dual Nature of Matter and Radiation”. Although as its wavelength decreases, its energy increases. As the frequency increases, energy also increases. These rays are produced in a discharge tube at a pressure below 0.01 rom of mercury. An electromagnetic wave has dual (wave–particle) nature. It was experimentally confirmed by German Physicist Heinrich Hertz. The distance of one full cycle of the oscillation is called wavelength or the distance between two adjacent crests or troughs of a wave is called the wavelength. wave nature as well as particle nature. Greater the magnitude of the charge on the particle, greater is the interaction with the electric or magnetic field and thus greater is the deflection. 02.26 Line Spectrum of Hydrogen 2.26 Line Spectrum of Hydrogen. Properties of Cathode Rays (i) Cathode rays are not electromagnetic rays. It can act as a wave and a particle as well. Bookmark added to your notes. Hence you can not start it again. Hz is of visible light. Such atomic matter is also sometimes. Hence, the matter is said to possess dual nature, i.e., it has both the properties of a particle and as well as a wave. The energy of the photon is related to the wavelength of electromagnetic radiation according to: Planck's constant. It is represented by ‘T’ and measured in seconds. Pro Lite, NEET Electromagnetic waves travel through the vacuum at a speed of 3 x 108 m/s. Electromagnetic wave theory This theory was put forward by James clark Maxwell in 1864.. 5. Electromagnetic radiations travel in space and vacuum through oscillating electrical and magnetic fields generated by their particles. Chapter-11: Dual Nature of Radiation and Matter Dual nature of radiation; Photoelectric effect; Hertz and Lenard’s observations; Einstein’s photoelectric equation-particle nature of light. Dual Nature of Radiation and Matter (chapter 11) Cathode Rays Cathode rays are the stream of fast moving electrons. Black body radiation. Electromagnetic radiation—light—is a form of energy whose behavior is described by the properties of both waves and particles. Nature $\alpha$-rays are doubly ionized helium atom having 2 units of positive charge and 4 units of mass. Velocity – The velocity of electromagnetic wave in vacuum is 3 × 108 m/s. The velocity of electromagnetic wave in vacuum is 3 × 10, m/s. CBSE class 12 chapter wise notes based on chapter 11, Dual Nature of Radiation and Matter, of class 12 NCERT Physics textbook are available in this article. This video is highly rated by Class 11 … 11.3.2 Hallwachs’ and Lenard’s observations. There is no charge on X-ray thus these are not deflected by the electric field and magnetic field. These rays are produced in a discharge tube at a pressure below 0.01 rom of mercury. Planck's Quantum Theory ,Structure of Atom - Get topics notes, Online test, Video lectures, Doubts and Solutions for CBSE Class 11-science on TopperLearning. Dual Nature of Radiation and Matter Important Questions for CBSE Class 12 Physics Matter Wave. If you are looking for solutions of NCERT Textbook problems based on this topic, then log on to Vedantu website or download Vedantu Learning App. It is represented by. Reasoning that radiation and matter should be symmetrical in nature, Louis Victor de Broglie attributed a wave-like character to matter (material particles). 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. Planck explain the distribution of intensity of the radiation from black body as a function of frequency or wavelength at different temperatures.
