Physics 6850: Modern Physics Lab I
Lab 9:35-13:30 Tuesday, Room 267, Physics Building
This is a two credit course.
The goal of the course is to learn some of the techniques of modern
experimental physics. This is done by the students repeating some of the
seminal experiments from the history of physics and investigations
into modern physics issues. Each student will
do five experiments and turn in a traditional lab report for four of them.
For the remaining experiment the student will have to present
the results as both a paper in the style of a scientific journal article and in
a 15 minute presentation in the style of American Physical Society
presentation. Examples of such papers and presentations will be given.
Professor: David Cinabro(333 Physics, 313-577-2918,
Office Hours: 9:00-11:00 Thursday
Text: The Art of Experimental Physics by Preston and Dietz,
John Wiley and Sons; 1991 is required.
- Lab Reports(50%)
Each lab report is due two weeks after the completion of the lab. It is
expected that students will work individually or pairs on each lab.
Lab reports are formal documents with the following parts:
The main goal of the lab report is to allow another student to reproduce
the experiment, not repeat the mistakes that were made, and act on
suggestions for improvement.
- Abstract - a one paragraph description of the experiment and
- Introduction - in general this explains why the experiment
is worth doing
- Experimental Setup and Technique - describes and diagrams the
apparatus, explains the basics of how the experiment is done,
and explains any formulae or theory used in the execution
of the experiment
- Raw Data - Shown in tables
- Data AnalysisExplains how the raw data is turned into
measurements of something else
- Error Analysis - Estimates errors, both statistical and systematic
- Results - Discussion and display of the results of the
- Conclusions - Comparison with expectations and thoughts
on what went wrong or how the experiment could be improved
- References - If previous works are used in any part
of the experiment they should be referenced here
- Lab Performance(25%)
Based on laboratory notebooks that are turned in
when experiments complete their data taking.
- Experimental Presentations(10%)
Based on a 15 minute oral presentations. These are expected
to be of the quality and style of
an APS presentation.
- Experimental Summary(15%)
Based on experiment summaries. These are expected
to be of the quality and style of a submission to a physics
journal such as Physical Review Letters. No more than
