The course Basic Principles of Physics II is the second course in the physics series of the program Science. It gives a general introduction to the concepts of electromagnetism, optics and light-matter interaction, essential for understanding complex phenomena beyond the territory of physics.

The course set the knowledge base for the laboratory course and follow-up classes on quantum mechanics, electrodynamics and special relativity. Also, it provides a guide to application of the principles and laws of electromagnetism and optics in chemistry and biology.
