Students are expected to acquire autonomy and ability to personal initiative in a Physics laboratory and be able to develop simple experimental projects from their elaboration to their implementation, analysis and discussion of results.
Especially, students are expected to master different experimental techniques;
Deepen the data analysis method and the comparison of results;
Develop critical sense and experimental logic;
Handle with rigour and caution the different measure instruments;
Use the computer for data acquisition, experiments control and analysis of the results;
Learn how to maintain a well-structured logbook;
Develop students’ abilities to communicate orally and in writing.
The curricular unit consists of a set of experiments whose objective is the demonstration of physical laws or the determination of essential physical constants. The experiments cover the following topics: Magnetic fields and forces; electric oscillations and resonance; electromagnetic waves, mechanical systems and Modern Physics.
- Ampere Balance: Calibration of a torsion balance; observation of the interaction forces between two currents; verification of Biot-Savart law; determination of the magnetic permeability constant; determination of the horizontal component of earth's magnetic field.
- e/m: observation of the flow of electrons in a magnetic field; verification of interdependence of the trajectory radius of electrons with their speed and intensity of the applied magnetic field; determination of the ratio between the charge values and the electron mass.
- Rotation Liquid: Observation of the surface of a rotation liquid; verification of the parabolic shape of this surface and its dependence with the rotational speed; determination of the value of acceleration of gravity.
- Microwaves: Building of a Michelson interferometer; observation of interference waves; determination of the wavelength of the studied microwaves; observation of the thin film interference of a wave; thin film thickness determination; observation of a frustrated total internal reflection (FTIR); determination of the index of refraction of a prism; determination of a tunnelling constant.
- Physical Pendulum (ruler): Observation of the dependence of the period of oscillation on the distance between the point of suspension and the centre of mass; determination of the moment of inertia of the ruler in relation to the axis passing through its centre of mass.
-Kater Pendulum: Observation of the oscillations in a reversible physical pendulum (Kater Pendulum); determination of the value of speed of gravity.
