Course Information

Item COURSE DESCRIPTION


PAP118 Physics Laboratory 1a / PHYS1P Physics Laboratory 1

[Academic Units: 2]

This course will train students in basic experimental physics that include topics in mechanics and basic wave optics. The laboratory sessions are designed to provide an active learning experience where key concepts can be better appreciated. Students will also learn about data acquisition, error analysis, error distribution and fitting procedures.

Item AIMS AND OBJECTIVES
  • To demonstrate some of the basic theoretical ideas in Physics.

  • To build a basic understanding of experimentation, data handling and error treatment.

  • To develop observational and analytical skills in experimental Physics.
  • To build scientific communication skills and encourage collaboration and exchange of ideas with peers and instructors.

Item ASSESSMENT

Students are continually assessed by:

  • Report (60%)
  • Viva (40%)

The weightage for each experiment is the same.

The score for E1: Uncertainty of measurements (exercise) will be taken as the score for one experiment.

There is no final examination.

Item SYLLABUS

Students are required to perform eight experiments in this course. The first 'experiment' is a written exercise designed to familarize students with the concepts of physical measurements and error analysis. The remaining seven are practical experiments. Please check the sequence of experiments that you and your lab partner will follow.

Experiment 1: Uncertainty in Measurements (Written Exercise)

In this exercise, students will learn the uncertainties involved in measurements, as well as the analysis of random errors. The concepts learnt will be applied to several subsequent experiments.

Experiment 2: Analysis of the Random Errors in an Experiment 

Students will find the position of resonance for the plunger in the air column of a resonance tube. Repetition will generate a set of data that is randomly distributed. Students will learn the origin of random errors, the Gaussian distribution of these errors and the Chi-squared test. Another objective of this experiment is to acquire Microsoft Excel skills for data handling and analysis.

Experiment 3: A Ball Rolling Down an Inclined Plane

The aim of this experiment is to find the angle of inclination of a plane for which the time taken for a steel ball to roll down the plane is the shortest. Through the experiment, students will learn about problem analysis, theoretical modeling, as well as experimental testing. Another objective is to introduce the topic of data rejection and its justification (Chauvenet’s Criterion).

Experiment 4: Air Track Collisions 

Conservation laws are among the most elegant and important laws in physics. This experiment seeks to reinforce students’ understanding of the concepts of elastic and inelastic collisions, linear-momentum conservation and energy conservation. Students will also learn about the limits of experimentation, the minimization of errors, the comparison of two measured numbers and the consistency of experimental data with conservation laws.

Experiment 5: Michelson Interferometer 

A Michelson interferometer is widely used for measuring unknown wavelengths of light and for measuring very small distances using known wavelengths of light. This experiment seeks to familiarize students with the working principles of the Michelson interferometer. Students will use the setup to measure the wavelength of the laser light source. They will be able to better appreciate the Michelson-Morley experiment used in the study of special relativity.

Experiment 6: Motion in a Viscous Medium 

An object falling in a fluid will experience a resistive force. Students will study the viscous drag on plastic beads falling in a column of dish-washing liquid. Through this experiment, they will gain a better understanding of Stokes' law and its limitations, as well as the properties of Newtonian and non-Newtonian fluids.

Experiment 7: The Bounce of a Ball 

Students will study the dynamics of a bouncing ball in this experiment. A motion sensor records the motion of a basketball; and a force platform measures the force that the bouncing ball delivers to it. Concepts such as the coefficient of restitution, impulse, change in momentum and energy loss will be investigated. This experiment also aims to provide some familiarity with the use of data loggers in the collection of experimental data. 

Experiment 8: Microwave Optics

This is an adaptation of the experimental competition of the 37th International Physics Olympiad held in Singapore in 2006. Traditionally, experiments like thin film interference and Bragg diffraction are carried out using visible light and X rays respectively. Using microwaves for these experiments will drastically transform the scale of the experiment - nanometers become centimeters, enabling the easy manipulation and observation of components and variables.

Item IMPORTANT INFORMATION

Attendance is compulsory for all official lab sessions. Absence must be accompanied with valid reasons or a medical certificate. Otherwise, you will not receive any marks for that experiment. Only students who are absent with valid reasons will be granted makeup lab sessions.

You are required to download and read the lab manual before coming to lab class. Please bring along your own copy of the lab manual to the lab.


Be punctual for all lab sessions - you may not be able to finish the experiment or have time for viva otherwise! Do bring along a calculator.You are required to purchase an A4 sized Experiment Log Book (from the Popular bookstore in the campus) for recording your experimental observations. The instructor will check and endorse on it at the end of the lab session. Please use the same book throughout the whole course.

During the lab session, the instructor will assess you orally on the experiment. Such viva sessions (weightage: 40%) are designed to test your understanding of the experiment and the concepts involved, as well as for you and your instructor to further discuss the experiment.

Each experiment is to be done in pairs, with your lab partner. However, you need to submit your own lab report. The lab report can be hand-written or type-written. All graphs must be plotted using MS Excel. Please read 1st Year Physics Teaching Lab: General Guidelines for Writing a Lab Report for an idea of how to write a report.

Students are reminded that plagiarism is a serious offence. Offenders will be penalized.


The lab report is due 1 week after the date of your experiment. Submit a hardcopy of your report to the First Year Lab. For each working day late, there is a deduction of 5% off your raw score for that experiment.


Item GENERAL LAB RULES

Follow all the precautions stated in the lab manuals!

Eating and drinking are not allowed in the lab.

Avoid wearing clothes or accessories that hinder your work. Tie up long hair, so that it does not get caught in the apparatus. You are advised to wear proper shoes.

If you injure yourself or are feeling unwell, inform the instructor immediately.

If you need to try out your own procedures which are not stated in the manual, approach the instructor for advice.

Exercise care (and some common sense) when working with the equipment.

You may use the computers in the lab for doing your lab report or data analysis. You are not allowed to play music or videos or games as they disturb your peers who want to do serious work. If you do not need your files anymore, remove them from the computer. Try not to save your files in the computer as you may find them gone or maliciously altered the next time you use the computer. It is advisable to carry a thumb drive with you all the time.

Printing is not available in the lab.

Tidy up your work area once you are done with your work.
