Learning outcomes
At the end of the course, the student is familiar with the principles of metrology and can use the main measuring instruments to conduct experiments in mechanics, thermodynamics, and optics applied to materials. They can interpret data and perform error analysis.
Course contents
The measurement of physical quantities: the scientific method; systems of units of measurement of physical quantities; dimensional equations; measurement errors; represent and use uncertainties; significant digits and scientific notation; random uncertainties and systematic uncertainties; concepts of precision and accuracy; evaluation of the uncertainty of an experimental result; propagation of uncertainties; elements of statistical analysis of random uncertainties; treatment of systematic uncertainties; the normal distribution; the problem of data rejection; elements of probability applied to experimental physics.
Laboratory Reports: Methods and standards for writing a laboratory report and presenting results orally. Elements on linear fits and non-linear fits.
Theoretical bases and tutorials for laboratory experiments:
- Thermal phenomena in materials: measurement of thermal conductivity in metal rods.
- Electrical phenomena in materials: verification of Ohm's law.
- Radiation-matter interaction: characterization of a solar cell.
Readings/Bibliography
- Slides of the lectures, availble on Virtuale.
- Booklets on the experimental activities in laboratory.
- J. R. Tayor “An Introduction to Error Analysis: The Study of Uncertainties in Physical Measurements” University Science Books.
Teaching methods
- Frontal lectures with the use of blackboard and slides, available on virtuale
- Practical exercises on the error and data analyses.
- Three experimental work sessions in laboratories (mandatory attendance), with written reports.
Assessment methods
Oral interview, with discussion of the written laboratory experiences results (to be handed in at least 3 days before the exam date). The oral interview aims at assessing the acquired knowledge related to the topics discussed during the course. The discussion of the laboratory reports aims at assessing the level of experimental proficiency and the development of critical skills in handling experimental data. The final mark, on a scale 18-30 over 30, takes into account the scores achieved in both the oral interview and in the laboratory reports.
Teaching tools
Dedicated educational setups for laboratory activities.
