PH 2020 - Physics II–Electromagnetism/Optics3 lecture hours 3 lab hours 4 credits
Course Description
This course is the calculus based continuation of PH 2010 . The purpose of this subject is to acquaint the students with the fundamental laws of electricity, magnetism, and optics. Particular topics include: electrostatic vector fields, scalar potential, capacitance and dielectrics, energy and force in electrostatic systems, current, resistance and electromotive force, magnetic fields and forces, electromagnetic waves, laws of reflection and refraction, geometrical optics and image formation, and interference and diffraction. PH 2020 is taught in an integrated lecture-lab format. (prereq: PH 2010 or PH 2010A or EE 3051B , CH 200 or CH 200A or CH 200B or CH 2100H or CH 310 , MA 137 or MA 137A or MA 1410H , (coreq: MA 231 or MA 1420H or MA 3501 )
