Abstract
The paper gives the analytical solution to the one dimensional hyperbolic heat conduction equation in an insulated slabshaped sample that is heated uniformly on the front face with δ or laser impulse The solution results in a formula that enables to estimate the minimum mean free path of energy carriers in the sample to detect the second sound ie the thermal wave at the sample rear face A method of experimental data evaluation at the second sound effect is proposed which gives the thermal diffusivity of the sample and the parameters of heat propagation
