Learning objectives
The module of "Applied Physics II" is part of the Integrated Course
"Physical and Experimental Sciences". The module has been
designed to convey knowledge and understanding of basic physics
principles, providing an introductory basis for other disciplines including
Physiology, Health Physics, Radioprotection, Non-ionizing Radiations,
Electromagnetic Fields, etc.., that rely on the physical phenomenology on
make frequent use of it.
The course will also provide the conceptual basis for understanding a
number of major technologies that are used with increasing frequency. In
this sense, the module also aims to develop the students' attitude
towards independent study and continuing education on the application
of physical techniques to several fields.
As its final, but perhaps most important, goal, the course has been
designed to stimulate students to become more familiar with certain
common concepts, that are not always sufficiently explained in previous
studies, such as: light and its manifestations, also in relation to the
structure of the eye and its physical defects, fundamentals of electrical,
magnetic and nuclear phenomena, the laws that govern potential and
current, electromagnetic and nuclear radiation, perturbations induced in
means passed through and aspects of detection and control.

Course unit content
The module of "Applied Physics II" will deal with the fundamental
principles of electromagnetism and optics.
Applications and consequences on human body physiology and medicine
will be stressed. In particular, deeper insights will be provided into the
effects of electric currents on the human body, and the use of radiations
in diagnosis and therapy.

Teaching methods
Lectures will be held on-site in compliance with safety standards, provided that further instructions on the ongoing health emergency are not implemented. Supporting material will be available on the specific, student-reserved platform (Elly) and will include slide presentations, audio-video aids or video-recording of the lectures.
During lectures, the topics contained in the program of the
module will be illustrated and commented. Emphasis will be posed on the
applications to biology and medicine of basic physics principles, with
examples of how such principles can lead to quantitative predictions on
physiological and pathological phenomena.
In selected cases, the demontration of basic physics principles will be
illustrated, with the aim to introduce the students to the practice of
logical thinking and experimental approach.
Assessment methods and criteria
The achievement of the objectives of the modules "Applied Physics I" and
"Applied Physics II" will be assessed through a written exam, mainly
consisting in open questions on the topics of the course. This will allow to
ascertain the knowledge and the understanding of both the theoretical
bases and their practical consequences.
The written exam will possibly include the resolution of problems, to assess the
achievement of the ability to apply the acquired knowledge to a
simulated, though realistic situation.
All parts of the written exam will be equally weighted in the final
evaluation.
In case of the persistence of the health emergency, the exams will be conducted remotely, as follows:
structured written test conducted remotely (by Teams and Elly). The test consists of 30 multiple choice questions on the course contents (reference texts + documents uploaded to Elly during the course). There is no penalty for incorrect answers.
The final mark, reported directly on Esse3, will correspond to the arithmetic average of the assessments obtained in the written test.
