Lecture
This lecture covers the fundamental concepts of electromagnetism and optics, starting with the force of Coulomb, electric fields, and potential energy. It then explores the behavior of charges in electromagnetic fields, induction, and the principles of optics, including refraction, reflection, and optical instruments. The lecture also delves into the movement of charges in electric fields, the concept of dipole moments, and the relationship between potential energy and electric fields. Additionally, it discusses the formation of electric fields in dipole structures and the application of these concepts in devices like cathode ray tubes.
