Physics laboratory IV

Students perform previously arranged experiments in the field of spectral analysis of the obtained data. They analyze and present the results in a written report.

Mathematical physics II (1FAF16) Fizikalni laboratorij III (1FAF19)

1. INTRODUCTION: Reprise of basics concepts about: Fourier series, Fourier transform, discrete Fourier transform and 2D Fourier transform. Examples of application in experimental physics.

2. EXPERIMENT: Sound spectrum analysis from a plucked string and comparison with model

3. EXPERIMENT: Diffraction from a crystalline lattice, comparison between direct image, FT image and diffraction pattern

4. EXPERIMENT: Characterization of signal filtering by passive filters (high pass, low pass, band pass). Comparison with models.

5. EXPERIMENT: Characterization of lock-in bandwidth. Lock-in amplification of a weak signal.

6. EXPERIMENT: Ultrasound diffraction (FFT)

• By the end of this course student will be able to perform a complex experiment including these steps:

• preparation for the experiment, literature check

• measurement and computerized data collection

• statistical analysis of data, comparison with mathematical models

• writting a report of measurement and results of

• analysis defense of results

Each experiment is conducted according to provided written instructions, which contain a list of relevant readings.

• Examination of lab. notes
• Delivered reports
• Oral defense of reports
