### PH1020 Physics II

#### Course Details

Description:To enable the students to: a) descrie electromagnetic phenomena using the language of vector calculus. b) determine electric and magnetic fields arising from simple configurations of static charges as well as steady currents in vacuum and in matter. c) solve problems involving propagation of electromagnetic waves in vacuum and in matter. d) apply the methodology of quantum mechanics to simple systems.
