PHYS 100C Spring 2010

Revision as of 15:24, 23 April 2010

Welcome to Physics 100C webpage for Spring'2010 Quarter.

RECENT UPDATES:

• April 23: I wanted to give problem 9.24 in homework #3, but due to a typo it got listed as 9.25. You can do either one, in my opinion 9.24 is a little easier, and more interesting.
• April 19: Homework #3 (PDF), due April 26. Problems 9.19, 9.24, 9.27, 9.28, 9.30.
• April 19: Homeworks #1 will be handed back during Friday Lecture. Homework scores are posted here. Homework #1 Solutions (PDF)
• April 19: Lectures 9-11 (PDF) (rough outline): dispersion, waveguides.
• April 14: Lecture 8 (PDF) summary: We derived dispersion relation for a simplistic "mass on a spring" model for electron in EM waves (Section 9.4.3). Additional material: Group velocity animations - see applets here and here, and also wikipedia page with relevant references about slowing down light to bike/running velocities and "negative" speed of light.
• April 13: Office Hours this week are moved to Wednesday, April 14th at 3PM. My office is MH 3210.
• April 12: Homework #2 (PDF), Probs: 9.13, 9.14, 9.15, 9.16. Due Monday, April 19th before lecture.
• April 12: Lecture 7 (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)
• April 9: Lecture 6 (PDF) summary: We derived Fresnel Law (Reflection/Transmission coefficients) for 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 Mon April 12 at the beginning of the lecture, 10AM.

• April 9: For those interested in history of science (not required for this course) - Who discovered Snell's Law?
• April 7: Lecture 5 (PDF) summary: We derived equations for transmitted and reflected EM waves for a case of normal incidence (cont'd from Lecture 4), Section 9.3.2. We then derived a more general case of oblique incidence, derived three laws of relection/refraction from boundary condition alone. (9.3.3).
• April 7: Effective Friday, April 9 and for duration of the quarter, the lecture location for physics 100C has been changed to Peterson 103 from the current WLH 2206. The days/time remain the same: MWF 10-10:50 A.M.
• April 5: Lecture 4 (PDF) summary: We started deriving equations for transmitted and reflected EM waves for a case of normal incidence (9.3.2).
• April 5: Yesterday's 7.2 magnitude earthquake provides us with an example of transverse (S-waves) and longitudinal (P-waves) seismic waves. P-waves (P stands for primary) propagate faster than S-waves, a fact that was used to determine the structure of Earth's interior. During earthquakes we feel mostly Love waves - surface waves which decay more slowly away from epicenter, and which move more slowly than P-waves or S-waves. Cats and dogs, however, are more sensitive and can pick up P- and S- "body" waves, warning us of the surfaces "Love waves" to come (my dog was pretty useless at this task yesterday, though).
• April 2: Lecture 3 (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).
• April 2: Homework #1, due Monday April 12th (before class) is: Problems 9.2, 9.3, 9.5, 9.10 and 9.11 (PDF).
• March 31: Lecture 2 summary: we have discovered that light is an Electromagnetic Wave and derived EM waves in vacuum from Maxwell Eqs. (9.2.1, 9.2.2) (PDF)
• March 29: Why Homework Matters - 2009 PHYS 100C statistics showing correlation between homework, midterm, final exam and total student rankings.
• March 29: Lecture 1 summary: we covered waves in 1D (9.1.1-9.1.2), discussed transverse/longitudinal waves (9.1.4), refreshed Maxwell Eqs. (PDF). Please review these Formulas.
• March 29: Lecture Notes from 2009 version of PHYS 100C can be found here - use for preview of upcoming material, actual notes for 2010 may change a bit.
• March 23: Syllabus has been posted.
• March 22: Discussion session: Fridays 3:00PM-3:50PM, WLH 2115.
• March 22: RSS and Atom feeds allowing you to subscribe to/monitor changes to this page are available from this webpage (links in lower left panel).
