EXTRA Material
Error Propagation rules.
Example of error propagation (applied to calorimetry).  In this PDF file, I have taken a student's lab measurements (top left side) and used them to calculate the specific heat of copper, CCu.
Old, hand written example of error propagation


This is the lab associated with Physics 232, Heat, Light and Sound. You will have an informational meeting on the first week where you will be assigned your first lab.

Manual: You need to buy "Physics 235 Lab Manual - Experiments in Heat, Light, & Sound".  It can be purchased in the Physics Office, Science Annex 107A, from Secretary Sherry Murino (afternoons).  It costs $10.  Please bring cash.  You can purchase the manual bundled with a notebook for $12.  If you buy the notebook alone, its $3.

Your final letter grade is determined based on your Informal and Formal Lab report scores.  The scores are determined by your TA with guidance (a rubric) from your instructor.  The Formal lab is worth twice as much as the informal labs.

Course Policies

Attendance  is essential for labs.  If you miss a lab completely you get a 0 for that particular lab.  If you miss and have a valid excuse (emergencies, sports or music activities, very sick) we can try to find another lab section for you to work in to make up the lab.  This must be okayed by the instructor of the other lab and you must make sure that you get your completed lab to your regular TA on time.

Calculators. I encourage you to have a calculator in this lab.
