Objectives

KNOWLEDGE AND UNDERSTANDING
Students will learn about the experiments that determined the birth of quantum mechanics, investigating the phenomenology of energy quantization, wave-particle duality and uncertainty principle.

APPLYING KNOWLEDGE AND UNDERSTANDING
Students will learn how to independently assess the main characteristics of scientific instruments, particularly power supplies, digital multimeters, digital oscilloscopes, spectrometers and radiation detectors, including working procedures, starting from written documents.
Furthermore, students will need to research bibliography and digital resources. Finally exporting and analyzing digital data will be required.

MAKING JUDGEMENTS
Students will have to identify unexpected experimental issues occurring in the laboratory, like the ones due to non-compliant set-ups, defective instruments or even phenomena that were thought to be irrelevant that turn out to be relevant.
It will be required form students a physical interpretation of experimental results through data analysis, plots and fitting procedures.

COMMUNICATION SKILLS
Students will be organized in laboratory groups composed by 3, maximum 4 people. Students will be encouraged to discuss within their group, with other colleagues, with tutors and the instructor the experiment scheme, its realization and interpretation of results.
Students will also learn how to present the experimetns and the results in a written scientific report.

LEARNING SKILLS
The goal will be the ability to design, implement, interpret and present an experiment. Particularly, students will be required to select the instrumentation adequate to the experimental needs, estimating the minimum desired specifications, and retrieve from bibliographic and digital resources the missing information on instruments and physical processes.

Prerequisites

Second year laboratory, General Physics II part

Contents

Experiments will deal with the topics covered in the 3rd year physics classes, namely the foundations of quantum mechanics, such as energy quantization, wave-particle duality and uncertainty principle.
The following experiments will be offered to students:
- Franck-Hertz tube
- Electron diffraction (Davisson-Germer)
- Atomic spectra
- Black-body emission
- Rutherford scattering
- Transistor
Experiments will be preceded by a classroom lecture. Students will prepare for the experiments and provide answers to preliminary quizzes on the moodle course page. The lab report will be due within 10 days after the experiment.

Teaching Methods

Experiments will be preceded by a classroom lecture. Students will prepare for the experiments and provide answers to preliminary quizzes on the moodle course page. The lab report will be due within 10 days after the experiment.

Verification of learning

Achievement of the course objectives will be evaluated as follows:
- Moodle quizzes to verify the knowledge concerning the experiment topics (knowledge and understanding)
- Instructor oral questions during lab experiments to verify the ability of applying knowledge and understading
- Written reports to verify communication skills
- Discussion of experimens and reports with the instructor to verify the ability to make judgements and learning skills.
Final grades will be determined according to the following criteria:
- 5% moodle quizzes
- 50% lab reports (at least 80% delivered before deadline)
- 45% oral discussion of experiments
