K. Chandrasekhara Vincenta Raman(C.V RAMAN)

Overview:

Sir K. Chandrasekhara Vincenta Raman (1888-1970), an Indian physicist, is known for his exploration of the molecular dispersion of light. For his discovery of this phenomenon, known as the Raman effect, he received the 1930 Nobel Prize in Physics.
Raman was born in Trichinopoly (now Tiruchirapalli) by Chandra Shekar and Parvati Amma. Raman was an avid reader since childhood. Three books among the great many books he read as a child had a lasting impression on the young Raman mind. These three books were "Asia Light", "The Elements of Euclid" and "The Sensations of sound". The last of these books was about sound waves. Later, when he grew up and had the opportunity to conduct research at the Association of India for the culture of Science, he decided to study musical instruments. He also published a book on the mechanical theory of musical instruments. So, as the Raman self admitted, humbly later, what he read in his schooling, paves the way for his future interests.
Raman was an early child-he finished his studies when he was eleven years old and joined the University of the presidency at the age of thirteen for graduation. There he could not impress his professors because he was not athletic as his father and seemed too young to be a college student. So, when he went to his first English course, the teacher asked him if he really belonged to the junior-class B.A. But very quickly, Raman proved to all his misinformed teachers by confirming his presence and first standing in his class. Their teachers were so impressed by their brilliance that they were forced to sit Raman for the ICS exams.
The Madras Civil surgeon said Raman physically unable to travel abroad to report the Indian Public Service review. Raman was not disappointed because he was not interested in a career other than scientific research. Raman Forever was grateful to this "great man"-the civil surgeon of Madras! He considered this a blessing in disguise and continued his higher education by choosing his favorite physical subject for his mastery he has most of the liberal attitude of his professors at the University of the presidency and ventured into the search in The bright waves. He reached a great height of fame in his chosen field and became the first pupil of the school to publish an article in the prestigious philosophical journal. It was also the highest rank of the university.
He married Lokasundari in 1907. Shortly thereafter, he was forced to sit in the Indian financial service, because he was unable to investigate his favorite topic due to financial difficulties. He was appointed deputy General accountant in Calcutta. There he met the Association of the Association "-India" for the Culture of Science, which offered laboratory facilities for the research enthusiasts. The day that Raman in the Indian Association for the Culture of science was a historical moment, because he wanted the laboratory of this association, where he and his team led legendary experiments on the light that the world knows today as "Raman effect". When Raman was given the first opportunity to study and experiment within the project, he decided to study musical instruments. He explained the performance of Ektara, a simple musical instrument. Raman also studied the physical nature of musical sounds and the mechanics of various musical instruments. He conducted a scientific study on the functions of the violin and even designed an innovative mechanical violin. He later studied the exploitation of several musical instruments and published numerous documents on the results of the research.
He was appointed professor of physics at the University of Calcutta in 1917 by Ahutosh Mookerjee, vice chancellor and philanthropist. During his journey through the Mediterranean, as he returned from his European journey after attending a conference, Raman discovered that the water molecules could disperse the light and the air molecules. He led him to the discovery of his famous "Raman effect". Raman continued as a professor until 1933 and was named after the head of the Department of Physics at the Indian Institute of Science in Bangalore. 1947 he became director of the Raman Research Institute, also in Bangalore. He became the Knight in 1929 and became president of the Indian Academy of Sciences in 1934.

Raman effect:

Raman effect, frequency change observed when the light is scattered in a transparent material. This phenomenon was discovered by the Indian physicist Sir K. Chandrasekhara Vincenta Raman in 1928. When monochrome light, like that of a laser, is transmitted through a transparent, liquid or solid gas and is observed with spectroscopy, the spectral line usually generated by the light is connected with lines of the largest length and less Wavelength, called Raman spectrum. These lines are caused by photons that lose by elastic collisions with the molecules of the transparent substance or gain energy. The Raman spectrum of a certain spectral line varies depending on the type of material that diffuses the light. The Raman effect is in the chemical analysis spectrographs and in the determination of the structure of the molecules of practical importance.

Raman Research Institute:

Institute of Raman Research, institution of higher education in the city of Bangalore. The institute was founded in 1948 by K. Chandrasekhara Ventaka Raman and until 1970 was executed by his personal means. After his death, the Institute was restructured and is now mainly funded by the Department of Science and Technology of the Indian government.

The Institute has active programmes for cooperation with several research institutes and universities at national and international level. The Institute's Library has a volume of 18 850 volumes and 22 000 periodicals. The most important scientific interests of Raman in optics, spectroscopy and vision are reflected in the main research areas of the Institute, including Astronomy and astrophysics, abbreviated matter, optics and physics.
