In the laboratory module, detailed studies of electromagnetism and optics are foreseen. Examples related to Chemistry will be provided.
The topics presented during the classroom lessons will be the subject of the experimental activities in the laboratory, which are aimed to teach the student the use of measuring instruments and the correct interpretation of experimental results by comparison with theoretical predictions.

In the classroom lessons of the laboratory module, the topics that will be studied in the experimental activities are presented:
- magnetism in matter: Maxwell's equations in vacuum, equations of magnetism in matter, classifications of magnetic substances, diamagnetism, paramagnetism and ferromagnetism (explanation in terms of microscopic laws and examples in Chemistry), magnetisation curve for a ferromagnetic material;
- physics of semiconductors: quantum numbers and energy levels, band theory of solids, Fermi's energy, electrical conduction in metals, insulators and semiconductors. Detailed study of semiconductors: electron-hole pairs, doped semiconductors, semiconductor devices (the junction diodes and the light-emitting diodes);
- principles of ray optics: light and electromagnetic spectrum, reflection, refraction, dispersion, prism, thin lenses, Kirchhoff-Bunsen spectroscope;
- principles of wave optics: Huygens's principle, Young's experiment, single-slit diffraction patterns, double-slit interference patterns, diffraction gratings, X-rays diffraction by crystals.

The topics of the laboratory experiments are:
- measurements of the hysteresis loop of a ferromagnetic material;
- measurement of the Planck's constant by using LEDs;
- calibration of a Kirchhoff-Bunsen spectroscope and measurement of the wavelengths of unknwown spectral lines;
- diffraction and interference of light, by using a laser and single and double slits.

The laboratory module consists in laboratory experiments, whose subjects are in-depth studied during classroom lessons preceding the experimental activities.

For the laboratory module, the suggested textbooks are:
- Mazzoldi, Nigro, Voci, "Fisica, Vol. 2", Ed. Edises
- Serway - Jewett, "Fisica per Scienze ed Ingegneria - Vol. 2", Ed. Edises
- Halliday, Resnick, Walker, "Fondamenti di Fisica", Ed. CEI

Oral exam with a discussion of the laboratory experiences.

Attendance for the laboratory experiences is mandatory in order to take the exam.
