(ii) Cathode rays are deflected by electric field and magnetic field. Dual Nature of Radiation and Matter Class 12 Physics MCQs Pdf. These oscillating electrical and magnetic fields are perpendicular to each other and to the direction of propagation of the wave. Find the energy of photon ? In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. Dual Nature of Radiation and Matter (chapter 11) Cathode Rays Cathode rays are the stream of fast moving electrons. Dual Nature of Radiation and Matter Class 12 Physics MCQs Pdf. 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 after reading this article you will be able to solve problems based on the topic. Class 11 Physics Physical World Fundamental Forces in nature The forces which we see in our day to day life like muscular, friction, forces due to compression and elongation of springs and strings, fluid and gas pressure, electric, magnetic, interatomic and intermolecular forces are derived forces as their originations are due to a few fundamental forces in nature. The wave associated with the particle is called a matter wave or a de Broglie wave. ... • Nature of Electromagnetic Radiation (Electromagnetic Wave Theory) This theory was put forward by James Clark Maxwell in 1864. 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. These rays are produced in a discharge tube at a pressure below 0.01 rom of mercury. Unit 17: Dual Nature Of Matter And radiation: Dual nature of radiation. These fields are transmitted in the forms of waves called electromagnetic waves or electromagnetic radiation. 6. There is no charge on X-ray thus these are not deflected by the electric field and magnetic field. Matter waves-wave nature of particles; de Broglie relation; Davisson-Germer experiment (experimental details should be omitted; only conclusion should be explained). Hence you can not start it again. As the frequency increases, energy also increases. As you can see in the above figure of the electromagnetic spectrum that as the wavelength of a radiation increases its frequency decreases. 1. Davisson-Germer experiment. Unit 18: Atoms And Nuclei Photoelectric effect, Hertz and Lenard’s observations; Einstein’s photoelectric equation; particle nature of light. Davisson-Germer experiment (experimental details should be omitted; only conclusion should be explained). 11.3 Photoelectric Effect. The theory of electromagnetic radiation was given by Scottish scientist Sir James Clerk Maxwell in the early 1870s. As the wavelength increases, frequency decreases and as the frequency increases wavelength decreases. Other characteristics of a wave are amplitude and period. This is possible only when you have the best CBSE Class 11 Chemistry study material and a smart preparation plan. Planck's constant is a physical constant named after Max Planck. Offer ending soon! Its wave nature is represented by its velocity, frequency and wavelength. They can travel in vacuum or space. Properties of Cathode Rays (i) Cathode rays are not electromagnetic rays. The concepts should be clear which will help in faster Its SI unit is Hertz which is represented as Hz. In this Chemistry video in Hindi for class 11 we explained wave nature of electromagnetic radiation. Thermodynamics Photoelectric effect. 02.26 Line Spectrum of Hydrogen 2.26 Line Spectrum of Hydrogen. As stated in the above section, electromagnetic waves are of many types and collectively they form electromagnetic spectrum. 4. Wavelength and frequency of a wave are inversely proportional.

On the other hand, photoelectric effect supported particle’s nature … Reasoning that radiation and matter should be symmetrical in nature, Louis Victor de Broglie attributed a wave-like character to matter (material particles). The energy of the photon is related to the wavelength of electromagnetic radiation according to: Planck's constant. Lect 04: Davisson and Germer Experiment This article is beneficial for class 12 students. 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. These rays are produced in a discharge tube at a pressure below 0.01 rom of mercury. 1 | P a g e (Visit for all ncert solutions in text and videos, CBSE syllabus, note and many more) Physics Notes Class 12 Chapter 11 Dual Nature of Radiation and Matter Cathode Rays Cathode rays are the stream of fast moving electrons. X-ray affects the photographic plate. The wave nature of light can be observed in the phenomena of interference, diffraction and polarisation. Electromagnetic radiations travel in space and vacuum through oscillating electrical and magnetic fields generated by their particles. diffraction etc., but it could not explain the following. 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. Particle Nature of Light × Sorry!, This page is not available for now to bookmark. Different regions of the electromagnetic spectrum are identified by various names. 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. Electromagnetic wave theory This theory was put forward by James clark Maxwell in 1864.. Electromagnetic radiation is a flow of energy in which electrical and magnetic fields vary simultaneously.
