This is a continuation of Fundamentals of Physics, I (PHYS 200), the introductory course on the principles and methods of physics for students who have good preparation in physics and mathematics. This course covers electricity, magnetism, optics and quantum mechanics.

Nearly 30 hours of video

25 lectures

Problem sets with solutions, midterm and final exam with answer keys



Ramamurti Shankar is the John Randolph Huffman Professor of Physics at Yale. He received his B. Tech in electrical engineering from the Indian Institute of Technology in Madras and his Ph.D. in theoretical particle physics from the University of California, Berkeley. He joined the Yale faculty in 1977 after three years at the Harvard Society of Fellows. He is dedicated to teaching and has published two texts: Principles of Quantum Mechanics and Basic Training in Mathematics: A Fitness Program for Science Students. His website has further details and a link to jokes collected by his students from Physics 200-201.
