A temperature wave propagates along a long thin bar of a metallic sample when subjected to periodic heating. In this way it is demonstrated that there is no wave nature in these improperly called thermal waves by showing that they do not transport energy and its propagation properties can be used to determine the thermal diffusivity of the material.
The purpose of this experiment is to understand the basis of heat flow, recognize heat conduction as a diffusive process by Fourier analysis, solutions of the heat equation, decompose an oscillation into its harmonics, observe different harmonics and how they damp with different rates and ultimately calculate the thermal diffusivity of a metal.
