This is the syllabus for Physics 5, Winter 2005, at:
It will be updated steadily as the course goes on, so please visit it frequently.
I am Douglas Eardley, a professor of physics. My research lab is 5014 Broida Hall (across from the elevators), and this is where I will hold scheduled office hours. Office hours this week are 2:30-3:30pm Fri Mar 11. But note that I am often not in my Broida lab at other hours, and if you want to meet me at another time, email or call first to make an appointment. want to meet me, please email or call first to make an appointment. My email address is doug@kitp.ucsb.edu (always put "Phys 5" in the Subject) and my campus phone is 893-4072 (or -2280).
Final: Final Exam will take place Thursday, Mar 17, 8-11am in the classroom. The exam will open book, open notes, and will cover the whole course: Chaps 37-44. The nature of the exam will be similar to the Midterms, but longer: There will be both multiple-choice questions and very short problems. The best way to study for the final is to do, and review, the homework; and to review the Summary at the end of each chapter.
Midterm 2: Second Midterm Exam took place Tue, Mar 1, in class. The exam was open book, open notes, and covered Chaps 40-42 and the first half of of Chap 43. Exams have been graded and returned in class. Class did well, average was 43.9/50. Solutions are here, or try printer-friendly pdf.
Midterm 1: First Midterm Exam took place Tue, Feb 1, in class. The exam was open book, open notes, and covered Chaps 37-39 and the first half of of Chap 40. There were both multiple-choice questions and very short problems. Grading is complete and tests were returned in lecture. Class did well, average was 41.5/50. Solutions are here, or try printer-friendly pdf.
Lectures are held Tue Thu 8:00-9:15am in Room 1640 Broida Hall. The first lecture is Tuesday, Jan 4, and the last lecture is Thursday, March 10. Prerequisites: Physics 4 or 24. Recommended preparation: Mathematics 5C (may be taken concurrently) and Physics 5L (may be taken concurrently). Topics: Special relativity, blackbody radiation, Compton scattering, photoelectric effect, Bohr model, quantum mechanics, molecules, condensed matter, nuclear physics, elementary particles and cosmology.
Book: Sears and Zemansky's University Physics by Young and Freedman, available in the bookstore. Physics 1-5 all use this same book, so you probably already own a copy.
The TA is Iman Aghilian, office hours 2-3:30pm in the PLC, email: iman@physics.ucsb.edu
Laboratory sections meet Tuesday 1:00-3:50pm (the evening section is cancelled due to low enrollment). You must register separately for the lab section, as Physics 5L. Buy the Physics 5 Lab Manual in the Bookstore. Labs meet in Broida room 3324, starting Tuesday Jan 4; bring your Lab Manual, calculator, etc.
Grading will be approximately like this: Homework (on web) 30%, first midterm exam 20%, second midterm exam 20%, final exam 30%. The Lab is graded separately as Physics 5L.
Homework will be due Fridays, and must be done online at
Mastering Physics (Course ID MPEARDLEY0002). The first assignment is due Friday Jan 7, 10pm.
Registering for the online homework: When you login to Mastering Physics, it will
ask you for the new Course ID: enter MPEARDLEY0002 for Physics 5.

Hints for "Blackbody Radiation and Continuous Spectra":
Part C: When T is doubled, A goes to (A/2), because A is defined in terms of T. Part D: (See online Hint D.1a.) You must first correct for the distance, as follows. You can find the intensity I at the surface of the star, by multiplying the observed intensity by the squared ratio of distance/radius. (This is because the intensity falls off like the square of the distance). So first multiply the intensity I by (R/r)^2, where r=(radius of star), and R=(distance to star). | |||
