Course Structure

This course alternates 3 cycles of lectures in the Classroom with 3 corresponding cycles of practical sessions in the Lab. The course begins with a first cycle of lectures in the Classroom, which is followed by a corresponding first cycle of practical sessions in the Lab. Then we continue with the second cycle of lectures in the Classroom, and so on.

The classroom lectures introduce the working principles of scientific instruments and present the experimental setups of some experiments aimed at illustrating electromagnetic and optical  phenomena, at verifying  natural laws, and  at measuring physical properties in the  same fields.  Procedures to analyze and ways to present the data that will be collected in the Lab are specifically highlighted.

During the cycles of practical sessions in the Lab the students actually perform the experiments and make the measurements  previously introduced by the  Classroom lectures.

During the periods devoted to lectures in the Classroom there are NO sessions in the Lab. During the periods devoted to practical sessions in the Lab there are NO lectures in the classroom.

Should circumstances require the lectures to be given online on in a mixed manner, some variations to the mechanisms illustrated above may become necessary, aiming however at fulfilling the planned course programme.

6 CFUs (corresponding to 7 hours each) are dedicated to lectures in the Classroom for a total of 42 hours, while 6 CFUs (corresponding to 15 hours each) are devoted to the practical sessions in the Lab with a total of 90 hours. Altogether, thus, this 12-CFU Course comprises 132 hours of teaching.

Required Prerequisites

Basic knowledge of experimental uncertainties and data analysis methods is mandatory.

Basic knowledge of mathematical analysis, electricity, magnitism and optics is important.

It is useful, and thus it is strongly recommended, to have already passed the exams of all General Physics courses.

Attendance of Lessons

Attendance to both lectures in the Classroom and experimental sessions in Lab is mandatory.

At both, student's signatures are collected in a sign-up sheet.

Classroom lectures are normally held 2 or 3 times per week, 2 hours each lecture.

Lab sessions are held normally 3 times per week, 2 hours each session.

Detailed Course Content

Description and subsequent execution of 27 experiments aimed to measure physics quantities and/or to verify physical laws in the fields of electromagnetism, optics and the most recent technological fields (solar energy). Analysis of the collected experimental data.

The detailed program is listed in the Section "Programmazione" (in Italian only).

Textbook Information

The teacher does  not follow any textbook specifically, but utilizes  material from different sources. Studying the slides  shown  during  the  lectures is normally adequate  to pass the  exam.

For the laboratory experiments, Instruction Manuals are provided. They can also be downloaded from the

Course web site (in Italian only): Instructions.

 

For students who wish to dwell deeper into the subjects of the Course, the  following list is a selection of textbooks and  other material concerning data analysis methods, electrical and  optical  instrumentation used in this Course, and  related experimental procedures.

Learning Assessment

Learning Assessment Procedures

The exams consists of: a) evaluation of a written scientific report on one of the experiments performed in the Lab; b) an oral discussion.

Upon completion of all Lab cycles the teacher assigns an experiment to each student. Students are given a deadline by which they all must deliver their written report to the teacher. 

For the oral discussion, 8 exam session are usually set for every Academic Year. Dates can be found in the official website of the Bachelor Degree in Physics Course: http://www.dfa.unict.it/corsi/L-30/esami.

It should be understood that these dates refer to the oral discussion only, as the written report should have been already delivered by all students at the end of the teaching period of the Academic Year in which they attended the course.
