Prof. C.V. Raman, was investigating about what makes larger water bodies appear blue during day time?
He came up with the proper reasoning on 28th Feb 1927 Absorption of blue colour (shorter wavelength) is less with respect to the longer wavelength. Shorter wavelength gets more scattered and hence we see larger wart bodies in blue colour. This gave rise to a new type of spectroscopy. Raman Spectroscopy and the effect is called Raman effect.
Raman received a Nobel Prize for his Raman effect in 1930, That was a rst Nobel Prize in Science for any Indian. Raman was totally educated in India. He did his B.A and M.A. in physics in India. He developed his own instruments (Spectrometer) for the studies. That means the instruments were also indigenous. That was a totally Indian discovery. Government of India has decided to celebrate the national Science day on 28th February every year.
Adhyayan develops new lecdemns (lecture cum demonstration) based on science every year. This lecdemn is delivered in different schools and colleges. Adhyayan celebrate whole February as National Science month. More than 200 lecdemns are delivered every year.
