PH 123 - College Physics II3 lecture hours 2 lab hours 4 credits
Course Description
The first section of this course covers the principles of electricity and magnetism. Specific topics covered include Coulomb’s law, electric fields, electric potential, capacitance, simple DC circuits and Ohm’s law, forces on charged particles in magnetic fields, and magnetic fields due to electric currents. The last section of this course covers the principles of geometric and physical optics. The laws of reflection and refraction are discussed, and these laws are used to study the ways in which mirrors and lenses can be used to form images. Interference is discussed and applied to double slits and thin films. The associated laboratory is designed to give students direct experience with the concepts presented in lecture. The laboratory also serves to familiarize students with laboratory techniques and equipment. This course replaces PT 220. Not for credit for students who have credit for PH 2020 or PH 2021 or PT 220. Designated as a laptop course. (prereq: PH 113 )
