Modern Physics By Sehgal Chopra Sehgal: A Comprehensive Textbook for Undergraduate Students


Modern Physics is a textbook written by D.L. Sehgal, K.L. Chopra and N.K. Sehgal, published by Sultan Chand & Sons. It covers various topics in modern physics, such as relativity, quantum mechanics, atomic physics, nuclear physics, solid state physics and electronics. The book is designed for undergraduate students of physics and engineering, and provides a clear and concise explanation of the concepts and principles, along with numerous solved examples and exercises.


The book has nine chapters, each divided into several sections. The first chapter introduces the basic concepts of modern physics, such as frames of reference, inertial and non-inertial systems, Galilean transformation, Michelson-Morley experiment, postulates of special relativity, Lorentz transformation, length contraction, time dilation, mass-energy relation and relativistic momentum and energy. The second chapter deals with the theory of relativity, covering topics such as relativistic kinematics, relativistic dynamics, Doppler effect, twin paradox, general relativity, gravitational redshift and bending of light.


The third chapter discusses the quantum theory of radiation, including topics such as blackbody radiation, Planck's hypothesis, photoelectric effect, Compton effect, Bohr's theory of hydrogen atom, de Broglie hypothesis, wave-particle duality and Heisenberg's uncertainty principle. The fourth chapter covers the quantum mechanics of one-dimensional systems, such as Schrodinger equation, potential well problems, tunneling effect and harmonic oscillator. The fifth chapter extends the quantum mechanics to three-dimensional systems, such as hydrogen atom, angular momentum operators, spin angular momentum and Pauli exclusion principle.


The sixth chapter explores the atomic physics and spectroscopy, covering topics such as atomic spectra, Zeeman effect, Stark effect, X-ray spectra, Raman effect and molecular spectra. The seventh chapter deals with the nuclear physics and radioactivity, including topics such as nuclear structure and properties, nuclear models, nuclear reactions and fission, nuclear fusion and energy sources, radioactivity and decay laws, alpha decay and beta decay. The eighth chapter covers the solid state physics and electronics, covering topics such as crystal structure and bonding, lattice vibrations and phonons, free electron theory and band theory of solids, semiconductors and devices.


The ninth chapter provides an overview of some selected topics in modern physics, such as lasers and masers, superconductivity and superfluidity, nanotechnology and nanomaterials. The book also contains appendices on mathematical tools for modern physics.


Modern Physics By Sehgal Chopra Sehgal is a comprehensive textbook that covers the syllabus of various universities and competitive examinations. It is written in a simple and lucid language that makes it easy to understand for the students. It also provides a large number of solved examples that illustrate the application of the concepts and principles. It also provides a large number of exercises that test the understanding of the students.


The book is available in both hardcover and paperback editions. It can be downloaded in PDF format from various websites on the internet. However, some websites may require registration or payment to access the PDF file. Therefore, it is advisable to check the authenticity and legality of the website before downloading the file. a474f39169
