Resumo

This paper describes the concept and principal features of thermal waves using a phenomenological approach. The role played by thermal waves in photothermal techniques is explained using different examples, ranging from the so-called purely thermal wave interferometry to photoacoustic spectroscopy. Some examples concerning the optical and thermal characterization of liquids and their application are presented.
