This course on Quantum Mechanics aims to introduce learners to the fundamental concepts and principles of quantum physics. By the end of the course, students will be able to understand the postulates of quantum mechanics, the failure of classical theories, and key experiments such as the photoelectric effect and Compton's effect. They will also learn about important topics like the Heisenberg uncertainty principle, wave functions, operators, observables, and the Schrödinger equation. The course teaches skills such as analyzing wave functions, calculating expectation values, and interpreting probability current density. The teaching method includes lectures on theoretical concepts, demonstrations of experiments, and problem-solving sessions. This course is designed for students pursuing B.Sc or M.Sc in Physics, as well as those preparing for exams like NET-JRF, GATE, UPSC, and JAM in the field of physics.
