The main points of this theory are: 1)The energy is emitted from any source continuously in the form of radiations and is called the radiant energy.

From both sun and wind. Economics Chapter 1 Development – Notes & Study Material, Geography Chapter 6 Manufacturing Industries – Notes & Study Material. It will be equal to the reciprocal of the wavelength. In other words, the system formed by these two first-order equations represents electromagneti… Electromagnetic Waves come in many varieties, including radio waves, from the ‘long-wave’ band through VHF, UHF and beyond; microwaves; infrared, visible and ultraviolet light; X-rays, gamma rays etc. It is represented by ν (nu) and is expressed in hertz(Hz) or cycles/second or sec-1. Chapter 2 is devoted to the treatment of transmission line theory. it is the best notes for studying board As red light has minimum frequency and yellow light has higher frequency, therefore the body on heating becomes first red,  then yellow and so on. This is a textbook on electromagnetic wave theory, and topics essential to the understanding of electromagnetic waves are selected and presented. energy energy, in physics, the ability or capacity to do work or to produce change. Relation between velocity ,wavelength and frequency of a wave. It is represented by  λ (Lambda) and is expressed in A° or m or cm or nm or pm. 1)The electrons are ejected only if the radiation striking the surface of the metal has at least a minimum frequency(νo) . Electromagnetic Wave Theory, Part 2 contains the proceedings of a Symposium on Electromagnetic Wave Theory held at Delft, The Netherlands in September 1965. It also analyzes reviews to verify trustworthiness. Chapter 1 presents fundamental laws and equations for electromagnetic theory. Has a clear and easily understood presentation of the kDB system which is useful for anisotropic materials. 3)The number of photoelectrons ejected is proportional to the intensity of incident radiation. Please try again. Kong explains most topics very clearly through words and examples, and I thoroughly enjoyed the small snippets that were written about many influential scientists that were sprinkled throughout the text. Previous page of related Sponsored Products, Discover the most mind blowing Secrets around you that you don't even know exist. The minimum energy required to eject the electrons is called work function( Wo). Its value is 6.626 × 10 -27 erg sec or 6.626 × 10 -34 joule sec. An electromagnetic wave can also be described in terms of its energy—in units of measure called electron volts (eV). Enter your mobile number or email address below and we'll send you a link to download the free Kindle App. Electromagnetism is defined as the combination of alternating electric and magnetic fields created by accelerated charges that propagate out from these charges at the speed of light in the form of waves. 2If the frequency of the incident light is more than the threshold frequency ,the excess energy is imparted to the electron as kinetic energy. Topics covered include: waves in media, equivalence principle, duality and complementarity, Huygens' principle, Fresnel and Fraunhofer diffraction, dyadic Green's functions, Lorentz transformation, and Maxwell-Minkowski theory. She has started this educational website with the mindset of spreading Free Education to everyone. Wavenumber is defined as the number of waves present in 1 cm length. The electron will be detached from the metal atom only if the energy of the photon is sufficient to overcome the force of attraction of the electron by the nucleus.That is why photoelectrons are ejected only when the incident light has a certain minimum frequency (threshold frequency ν. : ), Your email address will not be published. The article below elaborates on the origin and theory of electromagnetic waves. To get the free app, enter your mobile phone number. Examples deal with guidance, propagation, radiation and scattering of electromagnetic waves, metallic and dielectric wave guides, resonators, antennas and radiating structures, Cerenkov radiation, moving media, plasmas, crystals, integrated optics, lasers and fibers, remote sensing, geophysical probing, dipole antennas and stratified media. Prof. Kong passed away in March 2008 (age 66). Bring your club to Amazon Book Clubs, start a new book club and invite your friends to join, or find a club that’s right for you for free. Wavelength of a wave is defined as the distance between any two consecutive crest or trough. Last Updated on May 3, 2020 By Mrs Shilpi Nagpal 13 Comments.
