Physics laboratoriesLaajuus (3 ECTS)

Objective

The course illustrates to the student the experimental basis of physics. It gives the student insight in how the physical laws and equations introduced in the physics theory courses can be tested. It also gives to the student a versatile picture about both traditional measurement devices and modern computer based measuring systems which, for example, make possible real-time observation and data collection of time-dependent quantities.


-----
When completing this course the student gets experience in making measurements. The student learns to use a number of measuring devices in practice and becomes aware of the possibilities of modern measuring systems. The student learns applications of computer based measurement systems and sensors and achieves the skills of estimating measurement uncertainties and writing reports.

Content

Laboratory exercises and experiments are carried out by students working in small groups. Both traditional and computer based measurement systems are used. Students are also taught mathematical methods for analyzing data. In many experiments computers are applied for data collection, analysis and graphical display of data. Basic concepts of error analysis and uncertainty estimation are introduced. Students write reports including descriptions of the experimental arrangements and observations, data analysis, final results and uncertainty estimates.
