Esperimentazioni di Fisica I L. Martinelli
55 lectures, 16 labs (3-4h each)
Laboratory I, introductory course to the basic physics experiments, including measurement evaluation, display of results and error analysis.
Prerequisites: Fundamentals of Mathematics and Physics.
Assessment: practical (3h) + oral (1h) examination
Syllabus: Measurements of length,mass,time,temperature. Elements of probability and statistics: Definition and properties of the probability. Random variables, distribution functions, moments. Binomial,Poisson, Gauss and chi-squared distribution functions. Central limit theorem. Introduction to the sample theory; sample mean and variance; t- and F-variables. Data analysis: Error as uncertainty in a result. Systematic and random errors. Precision and accuracy of the measurements. Graphical representations of the measurements. Linear and non linear least-squares fitting. Goodness of fit: chi-squared test. Data manipulation: derivation and area integration, interpolation. Geometrical Optics: reflection and refraction. Mirrors and lenses. Practical work devoted: a) to use instruments (metre rule, vernier calliper, micrometer screw gauge, balance, timer, computer); b) to observe a physical phenomenon (behaviour of the period of a pendulum; rolling of a sphere down an inclined plane; distribution of a statreflection and refraction.
