If distributive inference occurs at the receiving end. This document is highly rated by JEE students and has been viewed 11388 times. The wavelength of the wave associated with any material particle was calculated as: In case of photon, if it is assumed to have a wave character, its energy is given by E = hν where ν is the frequency of the wave and h is Pla… Detail Course on "Atomic Structure" for Class 11: Electromagnetic Radiation(L-7) Sep 12, 2020 • 1h . Hindi Batches and Year Long Courses. soon. IIT JEE. Chemistry-XI. To assist you with that, we are here with notes. EM waves carry energy, momentum and angular momentum away from their source particle and can impart those quantities to matterwith which they interact. The pressure exerted by EM waves is known as Radiation pressure. Although the wave nature of electromagnetic radiation explains phenomena like ‘diffraction‘ and ‘interference’, some other important features remain unexplained. EM waves are used for communication purposes, voice communication in mobile phones, telecommunication used in radio. Lect 03: Equation of Electric & Magnetic Field. Name Date Class The Nature of Electromagnetic Waves (pages 70–73) What Is an Electromagnetic Wave? • Light travels through the vacuum of space – unlike sound. [2] Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields that propagate at the speed of light through a vacuum. | EduRev Class 11 Question is disucussed on EduRev Study Group by 118 Class 11 Students. 11.5 Particle-like nature of EM radiation (ESADM) When we talk of electromagnetic radiation as a particle, we refer to photons, which are packets of energy. [3] Electromagnetic waves are emitted by electrically charged particles undergoing acceleration,[4][5] and these waves can subsequently interact with other charged particles, exerting force on them. Free classes & tests. CBSE Class 11 Chemistry Atomic Structure– Get here the Notes for CBSE Class 11 Chemistry Atomic Structure. EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. EMR of visible or lower frequencies (i.e., visible light, infrared, microwaves, and radio waves) is called non-ionizing radiation, because its photons do not individually have enough energy to ionize atoms or molecules or break chemical bonds. Wave Nature of Electromagnetic Radiation, Absorption, Application of wave nature - Dual Nature of Radiation & Matter, NCERT Textbook - Dual Nature of Wave and Radiation. Log in Sign up. wave nature of electromagnetic radiation and it's characteristics. Dual behavior of electromagnetic radiation; CBSE Class 11 Chemistry Syllabus 2017 – 2018 . The various classifications and origins of electromagnetic radiation related to radioactivity and relativistic subatomic particles are discussed including gamma radiation, annihilation radiation, Cherenkov radiation, x-radiation, bremsstrahlung, nuclear bremsstrahlung, and synchrotron radiation. Contrarily, wave nature is prominent when seen in the field of propagation of light. The effects of these radiations on chemical systems and living tissue are caused primarily by heating effects from the combined energy transfer of many photons. The wave associated with the particle is called a matter wave or a de Broglie wave. The frequency is $$\text{7} \times \text{10}^{\text{14}}$$ $$\text{Hz}$$. Vectors; Class-XI. The unexplained observations are: Black-body radiation i.e. Learn vocabulary, terms, and more with flashcards, games, and other study tools. As they carry energy and momentum, they exert pressure. PLAY. But as you look closer, you see that the line is made up of thousands of separated black ants. Start studying Nature of Electromagnetic waves. The position of an electromagnetic wave within the electromagnetic spectrum can be characterized by either its frequency of oscillation or its wavelength.
