Physics 320: modern physics, fall 2011




Our lab will meet on Monday and Wednesday from 1:30 to 4:30 p.m. in the basement of Dana.  You will not necessarily be in lab every one of those days, but you should reserve those afternoons until we announce the forthcoming lab schedule and you have the chance to make plans with your partner.  In addition to the Experiments listed below, we will also explore selected Physlet-based Labs during lab time.  You can access those exercises via the link below. 

Laboratory attendance is somewhat flexible, to be coordinated with me and your lab partner, but the minumum expectation is that you attend lab on either Monday or Wednesday of each week. You are required to keep a laboratory notebook in which you will record your day-to-day work.   Always begin your entry with the date, time, and name of any lab partners. Dates recorded in the lab book must be the dates on which the entries are made. You are encouraged to work together when taking data and analyzing your results but you may not copy work from one another.  If you are not in the laboratory when the data is being taken, you should not include it in your notebook.

The main goal of keeping a lab book is to save time by keeping a careful record of what you have already accomplished.  Your notebook should always include:

* A diagram of your experimental setup if not shown on the lab webpage* Instrument settings
* Sketches of oscilloscope traces and other important visual results
* Data and analysis, including documentation of any associated files
* Sample calculations
* Interpretation of your results
