Temperature oscillations in a metal: Probing aspects of Fourier analysis (2.3)
| Student's Manual | This experiment illustrates the basic concepts of Fourier Analysis using simple experimental setup. We will also measure the propagation speed of thermal oscillations, analyze the heat equation and calculate the diffusivity of the material
under consideration. |
| LabView Code | LabVIEW Data Acquisition File |
| Sample Results | Discrete fourier transform of data collected over 4500 seconds at 0.005 Hz. Note the presence of odd harmonics only. Complete temperature profile at 0.005 Hz. Dynamic equillibrium is reached after 2400 seconds. |
