This course introduces students to the fundamental principles of quantum mechanics — the branch of physics that explains the behavior of matter and energy at atomic and subatomic levels where classical physics fails. Topics covered include wave-particle duality, Heisenberg’s uncertainty principle, energy quantization, potential wells and barriers, atomic structure, nuclear fission and fusion, and elementary particles.

Students learn to distinguish between classical and quantum physics, apply mathematical tools (like the Schrödinger equation) to solve simple quantum problems, and understand how quantum theory explains phenomena such as the photoelectric effect and blackbody radiation.
