Electromagnetic Theory And Modern Optics Physics Pragati

       Electromagnetic Theory and Modern Optics is a comprehensive textbook designed for B.Sc. 2nd Year, 3rd Semester students, authored by Dr. J.P. Agarwal and Dr. Amit Agarwal. Published by Pragati Publication, Meerut, this book covers two crucial subjects in Physics: Electromagnetic Theory and Modern Optics. It spans a total of 592 pages, divided into two parts, offering in-depth knowledge and understanding necessary for academic success and practical applications.

             Part-A: Electromagnetic Theory

Unit-I: Electrostatics

• Electric Charge & Densities: Explore the properties of electric charge, charge densities, and the forces between charges.
• Electric Field and Potential: Delve into the general expressions for electric fields and potentials using volume charge density, including divergence, curl, and Gauss’s law.
• Electric Dipole: Study the behavior of electric dipoles, polarization, electric displacement, electric susceptibility, and permittivity.

Unit-II: Magnetostatics

• Current and Magnetic Forces: Understand electric currents, current densities, and magnetic forces between current elements.
• Magnetic Field and Potential: Learn about the magnetic field’s general expressions using volume current density, including divergence, curl, and Ampere’s circuital law.
• Magnetic Dipole: Examine magnetic dipoles, magnetization, magnetic susceptibility, and permeability.

Unit-III: Time Varying Electromagnetic Fields

• Electromagnetic Induction: Study Faraday’s laws, Lenz’s law, displacement current, and Maxwell-Ampere’s circuital law.
• Maxwell’s Equations: Derive and understand Maxwell’s equations and their physical significance.
• Moving Coil Ballistic Galvanometer: Learn the theory and working principles of the moving coil ballistic galvanometer.

Unit-IV: Electromagnetic Waves

• Energy and Waves: Explore electromagnetic energy density, Poynting vector, plane electromagnetic waves, and their behavior in various media.
• Reflection and Refraction: Understand the laws of reflection, Snell’s law, Fresnel’s formulae, and Stokes’ law.

Part-B: Physical Optics & Lasers

Unit-V: Interference

• Conditions for Interference: Examine conditions for interference, coherence, Fresnel’s Biprism, Lloyd’s Mirror, thin films, and Newton’s Ring experiment.
• Interferometers: Study the Michelson and Fabry-Perot interferometers.

Unit-VI: Diffraction

• Types of Diffraction: Distinguish between interference and diffraction, study Fresnel’s and Fraunhofer’s diffraction, Half Period Zones, and zone plate.
• Optical Instruments: Understand the resolving power of optical instruments, including telescopes and microscopes.

Unit-VII: Polarization

• Polarization Techniques: Learn about polarization by dichroic crystals, birefringence, Nicol prism, retardation plates, and Babinet’s compensator.
• Optical Rotation: Study Fresnel’s explanation of optical rotation and polarimeters.

Unit-VIII: Lasers

• Characteristics of Lasers: Explore the characteristics and uses of lasers, spatial and temporal coherence, and conditions for laser action.
• Laser Systems: Understand three and four-level laser systems and their qualitative aspects.

This book is an invaluable resource for students aiming to master the principles of electromagnetic theory and modern optics, providing detailed explanations, practical examples, and comprehensive coverage of both subjects.
