What is the Raman Effect?

The Raman Effect was discovered by Sir C.V. Raman in 1928. It refers to the phenomenon where, when light scattered by molecules undergoes a change in frequency and results in the scattering of light at different wavelengths. This effect is used in spectroscopy to analyze the vibrational and rotational modes of molecules. This helps in various scientific and industrial applications....

Timeline of National Science Day

Year Event 1923 Austrian physicist Adolf Smekal describes the scattering of light effect, laying the groundwork for future research in this area. 1928 Soviet physicists Grigory Landsberg and Leonid Mandelstam observe the scattering of light effect in crystals, shortly before Indian physicist C.V. Raman publishes his groundbreaking theory on the same subject. 1928 Physicist Peter Pringsheim reproduces Raman’s theory of scattered light, coining the term “Raman Effect” to describe this phenomenon. 1986 The National Council for Science and Technology Communication (N.C.S.T.C.) proposes to the Government of India the declaration of February 28 as National Science Day, to promote science and scientific thought across the country. February 28, 1987 The first National Science Day is celebrated, marked by special events organized by the National Council for Science and Technology Communication. This includes the announcement of National Science Popularization awards, recognizing and rewarding outstanding contributions to science communication....
