Here you will find information for the undergraduate physics laboratories taught at the University of Rochester Department of Physics and Astronomy.  In Spring 2017,  Labs start Monday January 30 , 2017.  Dress Code:  Shoes should be worn to protect against falling objects.  Long pants should be worn to protect against accidental spillage.

Fall semester labs run from September to end of first week of December. There are NO labs during (highlighted yellow) the week of Fall break or during the week of Thanksgiving.  Lab Cycle is every two weeks as "A" and "B".

Spring Semester labs run from mid January to first week of April. There are NO labs during (highlighted yellow) the week of Spring break.

The A/B weekly cycle  for Spring 17 can be found at this link: Spring_2017_Week_Lab_Cycle.pdf
The A/B Lab calendar for Spring 17 can be found at this link: Lab_Calendar_S17.pdf

Statistics and Error Analysis

There is only one lab lecture for all course with labs (Mechanics, EM, Modern). For Spring 2017 the lab lecture on statistics is given on Friday January 20, 2017 at 3:25 pm in Hutch 141). For a PDF file of a lab lecture on statistics from previous years can be found at this link: manuals/Lab-Lecture-Statistics.pdf
Please also reference additional lab information at: manuals/LAB-Intro-information.pdf
Students should become familiar with the lab manual Error Analysis appendix B, which can be found at this link:  manuals/Appendix B

Lab Week A and Lab Week B Rotations

You should have signed up for a lab section when you registered for your physics course. The lab section which you signed up for should have had "Lab A" or "Lab B" included in the title. This is the lab week which you should attend. The calendar at the top right side of this page shows which lab sessions occur on which week,
You MUST attend the lab section for which you are registered.   Attending any other lab session without explicit permission from the lab admin  (physlabs.mechanics, physlabs.em or physlabs.modern) will result in an incomplete (IS) grade for that lab.   This is because each lab section can only accommodate 18-20 students.

 If you know you will miss a lab (illness, personal emergencies, etc.) you must make it up during the two week cycle period for that lab.   please email the lab admin  as soon as possible . In the mail to the lab administrator  you must state clearly your regular lab section, the lab section you are planning to attend and the reason.  Each student can be allowed to attend only one make-up lab.   If for some reason you do not hear back,  then show up in the section marked *MAKEUPS* on the list of lab sections below:

The Spring 17 Mechanics lab sections PHY121/181/113  (including makeup times) can be found here:LabSchedS17-Mechanics.pdf. (for a simplified version see: LabSchedS17-Mechanics-simplified.pdf.)

The Spring 17  E&M  PHY114/184 sections (including makeup times) can be found here: LabSchedS17-EM.pdf. (for a simplified version see: LabSchedS17-EM-simplified.pdf.

The Spring 17 Modern Physics PHY123/183  lab sections (including makeup times) can be found here: LabSchedS17-Modern.pdf.

The lab administrator emails are: physlabs.mechanics@pas.rochester.edu for PHY113 (fall,spring)  and PHY121(spring) and PHY181 (fall, Spring) labs.   physlabs.em@pas.rochester.edu   for PHY122/142/182 (fall)  and PHY114 (spring) and PHY182 and PHY184 labs.  physlabs.modern@pas.rochester.edu   for PHY123 and PHY183 Modern Physics Labs (spring).

Where are the labs held

Fall:
Mechanics labs in Fall semester (for PHY113 and 181) are held in room   B&L 267.
EM labs  i
n Fall semester (for PHY122, 142, and 182) are held in room  B&L 268
EM & Modern Physics labs in Fall semester (for PHY 114 and 184 ) are held in room B&L 165 (except for the first lab which is held in room B&L 268).
 
Spring:
Mechanics
labs in Spring semester  (for PHY113, 121, 121P and 181) are held in room B&L 267.
EM & Modern labs in Spring semester (for PHY114, and 184) are held in room  B&L 268
Modern Physics
Labs in Spring semester (for PHY 123 and PHY183)  are held in room    B&L 165.

Who to contact if you want to switch your lab section.

If your schedule changes and you need to make a permanent switch to another lab section, please contact Lysa Wade: B&L 252 - M, W, Th, F  9:30am-3pm, T 12-3pm  (Email:  lwade3@ur.rochester.edu)

Makeup Labs to Clear an Incomplete Grade from a Previous Semester

If you receive an  INCOMPLETE in a previous semester  and need to make up some of the labs this semester, you need to register as an Audit in PHY181 (for PHY113 and PHY121 labs),  PHY182 (for PHY122/142 labs),  PHY184 (for PHY114 labs), or PHY183 (for PHY123 labs).  The prelabs and postlabs grades for students who are making up labs missed in previous semesters are then recorded in blackboard pages of  PHY181, PHY182, PHY183, PHY184.  Make sure that your lab grade is recorded in blackboard by registering as an AUDIT in the appropriate lab course. In addition, to signing up as an Audit for the appropiate PHY18X course,  you need to sign up for an lab section in in the corresponding physics course.
Please bring an incomplete form to  Lysa Wade: B&L 252 - M, W, Th, F  9:30am-3pm, T 12-3pm  (Email:  lwade3@ur.rochester.edu)

General Remarks

In order to complete any of the Introductory Physics courses (PHY 113, 114, 121-123, 142, 181-184), you must complete (and pass) all five of the associated laboratory exercises. These labs provide a hands-on realization of a sample of the topics that are covered in the parent course.

Before you attend lab, you must download and print the lab manual, and complete the "prelab" section of the exercise. The prelab section will be collected at the beginning of the lab session. The worksheets in the lab manual (which you will fill out as you complete the lab) will be collected at the end of the lab session. Lab manuals may be downloaded from this website by visiting the lab manuals page.

You will need your completed prelab, a copy of the lab manual, a calculator, and a pen or pencil for each lab. You are also allowed to have your course textbook at your lab bench if you need it, but anything else (backpacks, etc.) must be put along the sides of the room or the back wall.

These laboratories can be interesting and educational if you arrive well prepared. Because your completed lab write-up is due at the end of the laboratory session, it is vital that you have read over the manual before coming to lab. If you haven't read the manual beforehand, you will lose time during the lab period that should be used for the lab itself, and may find yourself pressed for time at the end of the period.

In general, students work in small teams (two or three students) however each student must prepare their own report. It is recognized that students in a team will collectively discuss the experiment and the interpretation of the data, however students are not permitted to copy each other's write-ups.

Grading

All pre-labs and post-labs are graded by TA's according to same set of rubrics. The prelabs carry 2 points while the postlabs will be graded out of 20. Missing the lab will result  in an incomplete grade ('I') in the course. The grades for the prelabs and postlabs are recorded in blackboard. It is up to the instructors to decide how the laboratory grade will be counted toward the final course grade.

Grading Questions

Your grades will be displayed on blackboard after each lab is graded with all your lab grades to date. Please check to make sure that this is consisitent with the grade on your lab report. If you are missing a grade for a lab you completed or have a question about a grade, please email your lab section TA's.

Lab Manuals

Here you may download the lab manuals for your physics course. Please bring a printed copy with you to your lab session; the TA will not have extra copies. The prelab, the first page of the lab, will be collected at the start of the lab session. TA's will also make sure that the postlabs are blank before the experiment.
