The book is divided into 9 chapters, six chapters are related to electrodynamics and electromagnetic waves, and three are related. First chapter is related to motion of charge particle in different fields like electric field, magnetic field, and electromagnetic field, Bainbridge,s mass spectrograph, Thomson,s methods and working of C.R.O. is also explained in this chapters. Chapter two is related to Faraday law of electromagnetic induction giving an idea about Maxwell,s equations, and boundary conditions related to electic and magnetic fields. Chapters three is related to electromagnetic potentials. Chapter four is devoted to electromagnetic waves, covering Poynting vector, energy and momentum propagation of electromagnetic waves. Chapter five shows the reflection and transmission of electromagnetic wave in media covering the Fresnel,s relations, Brewster,s angle, modified field equation and total internal reflectiom. Chapter six is for radiation from an accelerated charge. Chapter seven give Einstein postulates of special theory of relativity, Michelson -Morley experiment, relativity of time, relativity of Lenght, relativity of velocity, stellar aberration of light , and Doppler effect in light. Chapter eight described the relativistiv dynanucsmvi, four vector, relatuvuty of mass and chapter nine is related to relativistic electrodynamics
