Title:

PHE-12, Physics Laboratory-III

Institution:

Indira Gandhi National Open University, India

Level:

Degree.

Description:

Physics is a way of looking at the physical world and finding ways of understanding it. And as students know, most of this understanding has been acquired through rigorous experimentation. Indeed, experimental physics has been nurtured by some of the finest intellects in the history of man. The lineage starts right from Galileo who with his simple experiments of rolling balls on inclined planes prepared the foundation for Newton's laws of motion, and then his law of universal gravitation. It continues with illustrious contributions from such geniuses as Newton, Huygens, Carnot, Joule, Thomson, Volta, Oersted, Ampere and Faraday, to name a few. Through the laboratory courses, our attempt has been to provide students with a flavour of experimental physics which has helped us enrich our understanding of the physical world. Although it may be that much of the fascination of experimental physics is subdued in an undergraduate course of this nature.

Along with the two earlier physics laboratory courses, this course aims at familiarising students with different measuring instruments, providing them opportunities of verifying well known relationships as well as probing new ideas and investigating physical problems experimentally. Students will learn to measure physical variables as accurately as possible and also be able to assess the possible errors involved in making measurements.

The University aims to provide this experience of practical work through a variety of experiments from optics, electronics and galvanomagnetic phenomenon. In addition, students will also engagte in some desktop exercises which will help them in analysing experimental data and establishing relationships between measurable physical quantities. It is hoped that the work through this course of experiements will provide students a sound basis for understanding physics.

Block 1: Experiment on Wave Optics:
1. Some investigations on the rotation of place of polarisation
2. Some investigations on interference of light
3. To study diffraction pattern of a thick wire
4. Resolving power of a telescope

Block 2: Experiments on Galvanomagnetic Phenomena and Electronic Circuits:
5. To investigate the temperature dependence of radiation from a hot filament
6. Study of magnetisation intensity in a magnetic material
7. Measurement of inductance: Anderson's Bridge
8. To study an off-balance Wheatstone Bridge and to investigate its use in the measurement of strain
9. Study of an audio frequency amplifier using bipolar junction transistor
10. Some experiments with logic gates
11. Study of Hall effect in a metal

Table-top Experiments:
1. Fourier analysis of periodic waveforms
2. Kepler's third law of planetary motion.

Assessment is by continuous evaluation during laboratory work (70%) and a final examination (30%).
