Book Description
Photoelectric effect - Light waves and photons - Einstein's photo- electric equation - laws of photo - electric emission - particle natureof energy - photoelectric equation - work function - photo cells andtheir application.Matter waves - wave mechanical concept of the atom - wavenature of particles - De-Broglie relation - De-Broglie wave length ofan electron - electron microscope.Concept of space, mass, time - Frame of references. Specialtheory of relativity - Relativity of length, time and mass with velocity- (E = mc2).The true nature of light is difficult to assess. Experiments showed thatlight exhibited wavelike properties of diffraction and interference. On theother hand, photoelectric effect indicates that light has the aspects of aparticle photon, with both energy and momentum. Thus light exhibits awave-particle duality.The wave-particle duality was extended to particles as matter waves byLouis de Broglie. His theoretical study on the nature of particles andwaves led to the invention of a new mechanics of particles calledquantum mechanics.

Book Description
"Modern Physics: Dual Nature of Radiation and Matter" explores the fundamental principles that govern the behavior of radiation and matter at the quantum level. From the pioneering experiments that unveiled the dual nature of light and electrons to the profound implications of Heisenberg's Uncertainty Principle, this book navigates through key discoveries and their impact on our understanding of the universe. It delves into how quantum mechanics revolutionized physics. With clear explanations and historical context, this book illuminates the intricate interplay between theory and experiment in shaping our modern worldview of the atomic and subatomic realms.

Book Description
Synchrotron radiation is the name given to the radiation which occurs when charged particles are accelerated in a curved path or orbit. Classically, any charged particle which moves in a curved path or is accelerated in a straight-line path will emit electromagnetic radiation. Various names are given to this radiation in different contexts. Thus circular particle accelerators are called synchrotrons, this is where charged particles are accelerated to very high speeds and the radiation is referred to as synchrotron radiation. Suitable for a summer short course or one term lecture series this text introduces the subject, starting with some historical background then covering basic concepts such as flux, intensity, brilliance, emittance and Liouville's theorem. The book then covers the properties of synchrotron radiation, insertion devices, beamlines and monochromators before finishing with an introduction to free electron lasers and an overview of the most common techniques and applications of this technology.

Book Description
Celebrated for his brilliantly quirky insights into the physical world, Nobel laureate Richard Feynman also possessed an extraordinary talent for explaining difficult concepts to the general public. Here Feynman provides a classic and definitive introduction to QED (namely, quantum electrodynamics), that part of quantum field theory describing the interactions of light with charged particles. Using everyday language, spatial concepts, visualizations, and his renowned "Feynman diagrams" instead of advanced mathematics, Feynman clearly and humorously communicates both the substance and spirit of QED to the layperson. A. Zee's introduction places Feynman’s book and his seminal contribution to QED in historical context and further highlights Feynman’s uniquely appealing and illuminating style.

Book Description
It is now nearly a century since special relativity reconciled seventeenth century dynamics and nineteenth century electromagnetism, yet physics students are almost invariably introduced to the subject as “MODERN PHYSICS” — and something of a mystery.This book, instead, treats special relativity as a useful branch of physics rather than as an astounding novelty. The emphasis is on its dynamical consequences, its effect on quantum mechanics (with all that this implies for chemistry and biology), the new insights that it provides in electromagnetism and its utility in problems such as calculating radiation from fast-moving charged particles. To avoid giving the impression that relativity somehow eliminates the distinction between time and space, 4-vector notation is not used until the latter part of the book.Since all the consequences of relativity arise from the Lorentz transformation, more than usual care is taken to show how it arises from simple notions about the uniformity of space and time, and the absence of any universal reference system at absolute rest. Recent studies in dynamics stress the critical difference between linearity and nonlinearity and so there is a proof that the transformation must be linear, something ignored by almost every other book on the subject.
