Léon Brillouin
Léon Brillouin was a physicist known for his contributions to physical acoustics, which is the study of sound waves and their interactions with materials. He introduced important concepts regarding how sound travels through different media and how it can be affected by various factors, such as temperature and pressure. Brillouin scattering, a phenomenon he discovered, involves the change in frequency of light when it interacts with sound waves, helping to analyze material properties. His work has implications in various fields, including telecommunications, material science, and medical imaging, advancing our understanding of sound and its practical applications.
