Physics Lab Course III
· This course introduces students to the methods of experimental physics.
· Emphasis is given on laboratory techniques such as accuracy of measurements and data analysis.
· The concepts that are learnt in the lecture sessions are translated to the laboratory sessions thus providing a hands-on learning experience.

List of Experiments
Section A
1. Using platinum resistance thermometer, find the melting pint of a given substance.
2. To determine thermal conductivity of a bad conductor by Lee’s method.
3. To determine ‘J’ by Calender and Barne’s method.
4. Determine the thermodynamic constant = Cp/Cv using Clement’s and Desorm’s method.
5. Study of variation of total thermal radiation with temperature.
6. To plot thermo emf versus temperature graph for Cu-Fe thermo couple and to determine temperature of a hot source (use sand bath).
Essential Readings:
User manual of the experiments are provided in the laboratory.
Section – B
1. Project
Details of Project
Students of Semester III are required to choose a topic for the project from a list approved by the department. They are required to perform a new experiment or carry out studies for writing a review article on a subject. At the end of the semester, a project report shall be submitted by each student. This project will be assigned to them at the beginning of the III semester.
Evaluation of Project:
A mid-term evaluation of the project will be made along with the CA test. This will carry 30 % of the total marks assigned for the project. At the end of the semester, the student shall be examined on the basis of project report submitted by her by a panel of external and internal examiners. The external appointed for the practical exam shall also evaluate the project along with the internal project supervisors. The evaluation of project will be based on presentation/viva-voce.
Total duration of practical exam and project evaluation shall be 5 hours.
