However, Peter Pringsheim was the first German to reproduce Raman's results successfully. He sent spectra to Arnold Sommerfeld. Pringsheim was the first to coin the term "Raman effect" and "Raman lines. Raman was honoured with a large number of honorary doctorates and memberships of scientific societies. In he was awarded the Franklin Medal. He was awarded the Lenin Peace Prize in He was moved to the hospital and the doctors gave him four days to live.
He survived and after a few days he refused to stay in the hospital as he preferred to die in the gardens of his Institute surrounded by his followers. Raman died from natural causes early next morning on 21 November Raman marg. Raman Road. Raman Hospital. He became professor of physics at the University of Calcutta in Studying the scattering of light in various substances, in he found that when a transparent substance is illuminated by a beam of light of one frequency, a small portion of the light emerges at right angles to the original direction, and some of this light is of different frequencies than that of the incident light.
His laboratory has been dealing with the structure and properties of diamond, the structure and optical behaviour of numerous iridescent substances labradorite, pearly felspar, agate, opal, and pearls. Among his other interests have been the optics of colloids, electrical and magnetic anisotropy, and the physiology of human vision. Raman has been honoured with a large number of honorary doctorates and memberships of scientific societies.
He was elected a Fellow of the Royal Society early in his career , and was knighted in He was the man behind the ground-breaking work of discovering Raman Effect. He also expelled experiments in the field of light scattering. All of these earned him the Nobel Prize for Physics. His discovery enabled for the first time, the mapping of possible levels of energy gains of molecules and atoms of a substance and thus discovered their molecules and atomic structure.
This discovery of the scattering of light led to the development of a simple alternative to infra-red spectroscopy, namely, Raman Spectroscopy. Raman Effect happens when molecules of a medium scatter light energy particles known as photons.
The spectrum varies with the nature of the transparent medium used to scatter the light. Raman Effect has proved to be of great scientific value and with its help the structure of more than compounds has been known.
He also gave us the scientific explanation for the blue colour of the sky and the ocean. He travelled widely abroad delivering lectures about his discoveries and researches.
Raman carried out experiments regarding the scattering of light by water and transparent blocks of ice which explained the phenomenon. He was a man of immense curiosity and a lively sense of humour with spirit of inquiry and devotion to science. Learn More in these related Britannica articles:. In , he was appointed as the first National Professor by the new government of Independent India. Meanwhile he continued to carry out different types of experiments and researches on the sun rays passing through water, transparent ice blocks and other media.
In , a science college was established in Calcutta and Raman was appointed its Principal. His mother Parvati was a cultured lady.
In Munich, some physicists were initially unable to reproduce Raman's results, leading to scepticism. He detected lines in the spectrum, which were later called Raman lines. Raman also worked on the acoustics of musical instruments. Raman has been honoured with a large number of honorary doctorates and memberships of scientific societies. Raman's father was a lecturer who taught mathematics and physics in Mrs A. In , Raman joined Presidency College in Madras where his father was a lecturer in mathematics and physics.

He sent spectra to Arnold Sommerfeld.
Raman died of a heart disease at the age of 82 in Bangalore,
Raman was a born genius and a self-made man and scientist with deep religious convictions. His contributions to the mechanical theory of bowed, stringed and other musical instruments like violin, sitar, cello, piano, veena, Tanpura and mridangam have been very significant.
In Prof. Ramachandran , who later went on to become a distinguished X-ray crystallographer. He worked out the theory of transverse vibration of bowed strings, on the basis of superposition velocities. These original research papers were of great scientific significance.
Nobel Prize is one of the greatest honor and recognition for a scientist. Raman was the second child of his parents, Chandrasekhar and Parvati Ammal and Raman was born in Tiruvanaikkaval, at his maternal grandfather's house. Raman left his highly paid government job to become a Professor of science.
However, Peter Pringsheim was the first German to reproduce Raman's results successfully. It was later edited and republished in Nobel Lectures. After 15 years at Calcutta he became Professor at the Indian Institute of Science at Bengaluru and since , he had been Director of the Raman Institute of Research at Bengaluru, established and endowed by him. For these experiments, Raman used a mercury arc and a spectograph. This discovery of Raman rendered the most valuable
