Chandrasekhara Venkata Raman. a great physicist, scientist, and Noble Prize winner, was born on November 7, 1888, in a Tamil- Brahmin family in Tiruchirappalli, Tamil Nadu. While his achievement of being awarded the Noble Prize in 1930 for his work on the diffraction of light, in the field of Physics, is most spoken about there is so much more done by this great man. Read on to know.

He was the first Indian to be appointed as the director of the Indian Institute of Science. This was an incredible achievement as all his predecessors were Britishers.
His research paper on the scattering of light was first published when he was still a graduate student.
He was honoured with the Bharat Ratna the highest civilian award in 1954.
In 1932, he discovered that photons of light exhibit angular momentum, along with his student.
In 1949, he established Raman Research Institute (RRI) in Bengaluru.
He worked at RRI as it’s director until his death on November 21, 1970.
Every year on February 28 National Science Day is celebrated in honour of the Raman Effect.This year's National Science day theme was Future of STI: Impact on Education Skills and Work.

THE RAMAN EFFECT

The Raman Effect is the process of scattering of light particles by molecules of a medium. The scattering occurs due to a change in the wavelength of light as it enters the medium.

Ask the right questions, and nature will open the doors to her secrets.

- C.V. RAMAN

In 1921, while on a sea journey to Europe, C.V Raman noticed the striking blue colour of some icebergs and the Mediterranean Sea. This perked his curiosity and he wanted to understand the reason behind the phenomenon.

After conducting experiments with transparent blocks of ice and light from a mercury arc lamp and recording the spectra from shining the light through ice came the result that would be famously known as the ‘Raman Lines’ caused by the ‘Raman Effect’.
