Which outcome occurs when a high-powered laser induces acoustic vibrations in a sample?

💡 Explanation

Brillouin scattering arises because induced acoustic waves create periodic density modulations that act as a moving diffraction grating; scattered light shifts in the frequency range. Therefore, Brillouin scattering occurs, rather than Raman scattering or other mechanisms, due to acoustic wave interaction.
