National Science Day is observed annually in India on February 28th. It commemorates the groundbreaking discovery of the Raman Effect by the celebrated Indian physicist Sir Chandrasekhara Venkata Raman in 1928. This scientific breakthrough earned him the prestigious Nobel Prize in Physics in 1930. National Science Day serves as a platform to promote scientific temper, inspire future scientists, and highlight the crucial role science plays in shaping our society.
The Legacy of Sir C.V. Raman
Sir C.V. Raman's discovery of the Raman Effect revolutionized our understanding of the interaction of light with matter. This phenomenon states that when light passes through a material, some of it is scattered and undergoes a change in wavelength. The Raman Effect has found widespread applications in various fields, including:
Chemistry: Analyzing molecular structures and identifying chemical compounds
Medicine: Non-invasive diagnosis of diseases and biomolecular imaging
Materials Science: Characterizing materials and studying their properties
Environmental Science: Monitoring pollutants and detecting trace substances
What is the Raman Effect?
Imagine shining light on a material. In most cases, the light simply passes through, potentially changing direction slightly due to a process called Rayleigh scattering. However, in the Raman effect, something different happens. A small portion of the light interacts with the molecules of the material, causing a change in its wavelength. This altered light is then scattered in different directions.
