Entry requirements

Algebra and geometry. Calculus. Mechanics I.

Aims

Electromagnetism and wave physics are fundamental parts of physics and have vast technical applications. The aim of the course is both to give basic knowledge in the electromagnetic fields and also an introduction to electrical measurements. The aim is also to give basic knowledge of wave phenomenon of both mechanical and electromagnetic origin.
