The objective of the course is the knowledge of the fundamental laws of electromagnetism and optics. General Physics Parts A and B is a prerequisite. The course is calculus based.

Current and resistance – Ohm’s law – Drude model – Joule effect – DC Circuits – Electromotive force
The magnetic field – Force on a moving charge and on a current – Torque on a current loop - Hall effect
Magnetic field of a current – Ampère’s law – Force between two currents – Magnetic flux
Magnetic properties of matter – Internal electronic currents and magnetization – Diamagnetism, paramagnetism, and ferromagnetism
Electromagnetic induction and Faraday’s law – Lentz’s law – The current generator -
Self-inductance – inductive circuits – Magnetic field energy – Mutual induction
Displacement current - Ampère-Maxwell’s law
Electromagnetic waves – Types of electromagnetic waves
Maxwell’s equations – Plane waves – Poynting’s vector – The electromagnetic wave spectrum – The speed of light
Ray optics – Reflection and refraction – Lenses and mirrors – Lens systems
Wave optics and Huyghens’ principle – Interference of light – The double slit – Multiple slits –Interference in thin films – Michelson interferometer
Diffraction by narrow slit – Resolving power of a lens – Diffraction grating – Basic spectroscopy – x ray diffraction
Polarization of light – Polarizers – Wave retarders – Brewster angle
