Surveys topics in classical physics intended primarily for students in pre-professional curricula and majors in various engineering technology concentrations. (Engineering transfer students should take PHYS 2120.) Topics include electricity and magnetism, wave mechanics, and geometric optics. A good working knowledge of algebra and trigonometry (at least at the high school level) is required before taking this course. Heavy emphasis is made for solutions to numerical problems. PHYS 2020 is the second semester of a two-semester sequence in general physics. (Many curricula require a laboratory course in physics. Students in these curricula must also take PHYS 2021.) Three hours of lecture each week.
