C. V. Raman (for Raman effect in metallurgy)

C. V. Raman was an Indian physicist who won the Nobel Prize in Physics in 1930 for discovering the Raman Effect. This phenomenon occurs when light interacts with molecules and changes its wavelength, providing insight into molecular structure. In metallurgy, the Raman Effect is significant for analyzing materials, as it helps identify their composition and properties by examining how they scatter light. This technique is non-destructive and valuable for quality control in metal production, enabling improved performance and innovation in materials science. Raman's work has had a lasting impact on both physics and engineering fields.
