General Physics II - Electricity and Magnetism 1200-1GENPHEM2
The course will introduce the fundamentals of electricity and magnetism and several related physics topics with emphasis of their applications in modern chemistry. We will use calculus based methods, e.g., relevant equations together with the corresponding differentials and integrals.
This class employs some use of modern learning technology, since physics teaching during Lectures will be reinforced by Peer Instruction pedagogical activities with i-clickers (https://www.iclicker.com/).
The course will start with introduction of electric fields and electric forces generated by point charges and dipols (permanent and electrostatically induced; molecular dipols). We will introduce a related Gauss Law. We will discuss the notions of free and bound charges, electrostatic induction, and related notions of electrical conductors and insulators. Then, we will discuss the notion of electrical potential, potential energy and work in electric field. Next, we will discuss charged isolated conductors and their capacitance, as well as dielectric permittivity and dielectric polarization of the matter. Macroscopic and microscopic views. Next, we will move from electrostatics to the description of moving charges. First, we will introduce an electric current and electric circuits in the cases of constant current (DC) and alternating currents (AC). We will introduce the Ohm’s law, the Kirchoff’s laws and electromotoric (emf) forces. Then, we will move into the description of the magnetic fields, magnetic forces and their effects on static and moving charges. We will derive the Ampere’s law and discuss the law of Biot-Savart. We will introduce magnetic flux, the Faraday’s law of induction and a related Lenz’s Law. We will discuss the inductors, self-induction and generalize the discussion about voltage, currents, impedance, electro-magnetic energies and power in resistance-inductance-capacitance DC and AC circuits. Next, we will combine previously discussed electro-magnetic equations towards their most generalized form, i.e., the Maxwell’s equations. We will discuss different forms of magnetisms. Next, we will apply Maxwell’s equations in description of electromagnetic waves. Then, we will move towards description of the main concepts of geometrical optics including reflection and refraction of light rays in various media. Next, we will describe several concepts related to treatment of light as a wave. Here, we will talk about light diffraction and interference. Finally, IF WE MANAGE TO HAVE SOME TIME LEFT, we will discuss some quantum physics concepts related to light (quantization of electromagnetic waves, photon emission/absorption, the photoelectric effect) as well as behavior of electrons in simple potential wells.

Learning outcomes
Learning outcomes consist on gaining conceptual as well as calculus-based knowledge of electricity and magnetism described in Maxwell’s equations as well as knowledge of other selected physics topics. Those other topics involve light passing rules described by light refraction, diffraction and interference as well as knowledge of the energy levels within simple atoms. The corresponding skills will involve: 1) applications of the Maxwell’s equations for static and dynamic point charges, dipols and high symmetry charged objects and 2) applications of the geometrical optics laws for passing of optical rays.
Assessment criteria
The course consists on Lectures, Recitations and a Physics Laboratory section. You will need to pass all three sections. A grade will be based on several one hour tests and quizzes (usually integrated within lectures and recitations), correct answers to iClicker questions and a final exam. A final grade will be assigned based on the total number of points (see below) gained during the WHOLE SEMESTER and special provisions described below.
During quizzes, tests and final exams students will be allowed to use calculators, but NOT their smartphones. Usage of smartphones is strictly prohibited during any kinds of tests as well as during lectures and recitations.
Attendance during lectures and recitations is required. The student is allowed to miss a maximum of ten (10) lectures during a whole semester, out of which at least four (4) must be justified and excused. Similarly, the student is allowed to miss a maximum of five (5) recitations during a whole semester, out of which at least two (2) must be justified and excused. In all the cases, justifications and excuses for absence will be accepted by a teacher only till seven (7) working days after finishing the cause for absence. In the case of being sick, a required form to excuse a given absence will be a written justification obtained from a medical unit affiliated with the University of Warsaw, such as CenterMed. Only, when the student cannot be physically present in Warsaw during illness, then other non-UW affiliated health entities might be considered, but advice of the head of the educational unit (EUH) might be sought beforehand in such cases after presenting the appropriate medical certificate by the student.
During the time of online education, only medical certifications explicitely stating that the student is unable to participate in the online test due to illness will be considered. Same rules as above apply.
The only way to repeat a missed Partial Exam will be also in accordance to the described above rules about excusing absences.
These rules were made in accordance with § 33 of the current UW Rules of Study.
In order to pass the course, you will need to pass a Physics Laboratory section set up within the Department of Chemistry UW. Passing Physics Laboratory section will be done based on the rules devised by the Laboratory Director.
Grade Points Scoring:
Partial exams during class(5 in total, last might happen in the last week of the semester beyond regular class hours): Only 4 best will be counted, each 150 pts = 600 pts
Homeworks (10): 15pts x 10 = 150 pts
Quizzes (10): 5pts x 10 = 50 pts
Final Exam: 200 pts
iCliker bonus points: 90 pts (2 pts. for each lecture)
Plusses bonus points: 10 pts
Total possible: 1000 pts. + 100 bonus pts.
Grade Assignment (in polish grading system)
900-1000+ pts. 5 (bdb)
