Summary
The physics course unit in the second year of the integrated preparatory programme (CPI) is organised into two sections: a disciplinary portion (called the "Physics section") comprising lectures and tutorials and an experimental portion (called the "Experimental Physics section") comprising practical work. These two sections are interdependent. > "EXPERIMENTAL PHYSICS" SECTION (4 ECTS) - Practical work no. 1: First-order linear filters: First-order high-pass and low-pass filters Harmonic transfer function, Bode plot, cutoff frequency and bandwidth. - Practical work no. 2: Second-order linear filters: Second-order low-pass and band-pass filters - Practical work no. 3: Network spectrogoniometer: Configuring and using a network goniometer - Practical work no. 4: Single-slit light diffraction: Diffraction patterns produced by single slits of different shapes. Experimental validation of the dependency law giving the characteristic size of the central diffraction task. - Practical work no. 5: Light interference with N waves: Interference pattern produced in monochromatic light by a wavefront division device with N waves, evolution if N increases. Experimental validation of the dependency law giving the interfringe of an interference pattern. - Practical work no. 6: Thermal conduction in a metal: Temporal change in temperature along a copper bar when there is a sinusoidal change in temperature at one end of the bar. Determining the diffusivity and thermal conductivity of copper. - Practical work no. 7: Measurement of liquid viscosity: Study of the influence of temperature on the dynamic viscosity of different fluids. Determination of the grade of an engine oil. - Practical work no. 8: Temperature sensors: Study of a thermistor, a platinum resistance probe and a thermocouple. Characteristics, sensitivity and linearity of a sensor.
Educational goals
The skills targeted are: > Metrology: - Identify the sources of errors when performing a measurement. - Evaluate an uncertainty (type A or type B evaluation when performing a direct or indirect measurement). - Express the result of a measurement by a value and the associated uncertainty with an appropriate number of significant figures. - Know how to compare a measured value with its uncertainty associated with a reference value. - Analyse the sources of uncertainty and propose improvements to the measurement process. - Use linear regression software. - Judge whether experimental data with uncertainties are consistent with a linear or affine model. > Electrokinetics: Practical work nos. 1 & 2 - Manage, in an electronic circuit, the constraints related to the connection between masses. - Display and determine the characteristics of a periodic electrical signal using a digital oscilloscope. - Implement an experimental device to study the frequency response of an electrical filter in sinusoidal conditions and determine its characteristics. - Experimentally draw the Bode plot (gain and phase shift) of an electric filter. - Understand the action of a filter on any periodic signal and highlight the influence of the filter characteristics on the filtering operation. > Optics: Practical work nos. 3, 4 & 5 - Configure and implement an autocollimator and a collimator. - Measure an optical wavelength using a network goniometer. - Compare several light diffraction devices: analogies and differences. - Compare several light interference devices: analogies and differences. > Thermal diffusion: Practical work no. 6 - Implement an experimental device for the thermal diffusion process in a metal. > Fluid mechanics: Practical work no. 7

Continuous Assessment
Comments: After each practical work session the students must write a report that will be marked.
There is also a final practical exam.
