PHYS 100C 2009
Welcome to Physics 100C webpage.
UPDATES: in reverse chronological order
- April 10: Q&A Notes (PDF) (mostly some andwers to questions Jeff keeps asking me during the lectures - not required reading material by any means, for general education only).
- April 9: Lecture 4 (PDF) summary: We derived equations for EM waves in conducting media. The solutions for wavevector now have imaginary component, which means the wave amplitudes are exponentially decaying over "skin depth" near the surface. E and B are still mutually perpendicular, but are out of phase. (9.4.1)
We also derived equations for transmitted and reflected waves for EM wave normally incident at an insulator-conductor interface. Perfect conductor has 100% reflection coefficient. (9.4.2).
- April 7: Lecture 3 (PDF) summary: We derived equations for transmitted and reflected EM waves for a case of normal incidence (cont'd from Lecture 2), See section 9.3.2. We then derived a more general case of oblique incidence, p-polarized wave; Discussed Brewster angle and applications (polarized glasses and Brewster Angle Microscopy. Section 9.3.3.
Reminder that HW#1 is due Thur April 9 at the beginning of the lecture, 8AM.
- April 4: Feel free to add feedback, comments or suggestions regarding the PHYS 100C course in the discussion section (anonymously or not). Please do not edit this (main) page.
- April 2: Problems 9.3, 9.5, 9.9 (sketch optional), 9.10, 9.15 (note that 9.13 will be deferred for HW #2) will be due as HW #1 next Thursday, Apr. 9 before lecture.
- April 2: Lecture 2 (PDF) summary: we have derived energy density, energy flux, momentum density and radiation pressure of EM waves (9.2.3), propagation of EM waves in Linear Media (9.3.1), defined boundary conditions for EM wave traveling across media boundary and formulated the Incident, Transmitted and Reflected waves (9.3.2).
- April 1: Lecture 1 (March 31) summary: we covered waves in 1D (9.1.1-9.1.2), discussed transverse/longitudinal waves (9.1.4), derived EM waves in vacuum from Maxwell Eqs. (9.2.1, 9.2.2).
- March 31: Change in policy - during the discussion session we will be breaking into small groups and solving problems, including (sometimes) upcoming homework problems. Therefore, student collaborations on homeworks is now allowed. Participation in discussion sessions is optional.
- March 31: Lecture 1 Notes posted.
- March 31: Discussion session: Fridays 11:00-11:50, WLH 2110.
