Prerequisites: Laboratory of Physics
Target skills and knowledge: The aim of this course is to acquire methods in the formulation and experimental verification of physical models applied to materials.
The statistical analysis procedures of experimental data are described and applied. The validation of physical models are applied to systems able to measure some fundamental physical properties of the materials.

The student in own develops:
- method in defining analytical models that describe physical phenomena,
- strategy in defining measurement experiment and the resulting data collection,
- critical sense to distinguish the various types of measurement errors,
- sensitivity in their interpretation after the statistical analysis,
- criticism in the evaluation in the qualitative and quantitative description of the analytical models
Examination methods: Reports of laboratory experience and oral discussion of the same.

The course is divided into three main laboratory experiences determined to measure three physical properties of materials:
the resistivity of metals,
the refractive index and
the Verdet constant linked to the electro magnetic properties described by the Faraday effect.

For each of the laboratory experiences, students must draw up a report that summarizes the theoretical models, the description of the instrumental apparatus, the methods of data collection, the methods of data analysis and, finally, the conclusions on the validity or not of the descriptive capacity of the theoretical model used to correctly represent the measured phenomena.

Students will be divided into groups of two people who will contribute with equal responsibility to the drafting of the reports.

During the examination the examinants will be required to describe and discuss the content of the reports justifying the results and the chosen presentation forms.
Assessment criteria: The ability to perform and critically analyze a laboratory experience in all its aspects, from the data taking to the writing of a report, and the knowledge of the theory of errors learned during the course will be evaluated.

The critical capacity of the data analysis will be evaluated and the ability to correlate the data to their analytical description and finally to specific properties of the materials.
Course unit contents: 2184/5000
• Part of data analysis and error theory.
The fundamental concepts of probability theory applied to the terior of errors are reviewed.
Venine introduced the concept of teria of decisions and acceptance and rejection of hypotheses of validity of theoretical models.
Methods for the fit of experimental data with theoretical models and the determination of calculation parameters are introduced.
In particular, the Chi Chi model is introduced as a functional minimization.
The concepts introduced are applied to the measurement of physical properties of materials.

• Resisiveness: The objective of this experience is to study the electrical conductivity of some metallic wires, in
particular we want to verify the first law of Ohm and its validity interval. Also you want
check also the second law of Ohm, that is the linearity relationship existing between the resistance e
the geometric characteristics of the conducting wire.

• Index of refraction: prism. The purpose of this experience is to observe the behavior of a light beam through a
triangular optical prism and study some properties and procedures related to the latter. Experiences are made to measure the dispersion of the refractive index as a function of the wavelength and then experimentally verify the law of Chauchy. The Lorenzts model is introduced to describe the response of insulating materials to electromagnetic radiation in the range of visible, near infrared and IR light. The complex analytical form of the index of refraction is deduced and therefore the interpretation of the real and imaginary pparte. The spectra of refraction and absorption of a material is made to determine the spectral dependence.

• Index of refraction: faraday law: The purpose of the experience is to study the Faraday effect, which is a magneto-optical phenomenon
of interaction between magnetic field and light in a medium (solid in our case) that causes one
rotation of the light polarization plane, varying the intensity of the field and the length
wave of light.
