This lecture introduces the concept of the electron, one of the fundamental particles of matter, which marks the beginning of modern physics. In this class, students will learn how scientists discovered the electron through experiments with cathode rays and how this discovery changed our understanding of atoms.
The lecture will cover the structure of the atom before and after the discovery of the electron, J.J. Thomson’s cathode ray experiment, and the determination of the charge-to-mass ratio of the electron. The concepts will be explained in a simple and exam-oriented way according to the NEB Physics curriculum.
By the end of this lecture, students will understand the basic properties of electrons, the historical experiments that led to their discovery, and the importance of electrons in modern physics.
