Life history of sir cv raman history

Raman spectroscopy extracts this information through the detection of Raman scattering from the sample. Both organic and inorganic compounds can be nondestructively analysed by the Raman spectroscopy. Spin of photons: With Suri Bhagavantam, Sir CV Raman determined the spin of photons inwhich further confirmed the quantum nature of light. Raman-Nath theory: With his student, Nagendra Nath, Sir CV Raman provided the theoretical description of the acousto-optic effect light scattering by sound waves in a number of articles which resulted in the Raman-Nath theory.

This effect has enabled optical communication components based on laser systems through the use of modulators and switching systems. Study on diffraction of light: He conducted theoretical and experimental studies on the effects of X-rays on infrared vibrations in crystals exposed to ordinary light, as well as on the diffraction of light by hypersonic and ultrasonic acoustic waves.

Study of crystal dynamics: InSir CV Raman took a novel approach to the fundamental issues of crystal dynamics by studying the spectroscopic behaviour of crystals. From tohe studied the structure and characteristics of diamonds. In the early s, he studied the structure and optical behaviour of many iridescent materials, including labradorite, feldspar, agate, quartz, opal, and pearl.

Other Interests: It includes the study of the optics of colloids and electrical and magnetic anisotropy. His last interests in the s were in biological properties such as the colours of flowers and the physiology of human vision. He was one of the recipients who got the Bharat Ratna for the first time in along with S. Radhakrishnan and C.

Raman, a lunar crater, is named after Sir CV Raman. The then-Indian government agreed and announced the day as National Science Day in February 28,marked the first National Science Day. The theme "Global Science for Global Wellbeing" was chosen to increase public understanding of the scientific issues in a global context that are affecting global well-being.

Bohr Millikan M. Wilson O. Siegbahn K. Hans Fischer Germany. Sinclair Lewis United States. Raman India. Karl Landsteiner Austria. Nobel Prize recipients He has a Master's in Physics from the same college and broke all the previous records.

Inhe married Lokasundari Ammal and had two sons, namely Chandrasekhar and Radhakrishnan. Inhe went to Calcutta now Kolkata and joined as an assistant accountant general. But in his spare time, he went to the laboratory to do research at the Indian Association for Cultivation of Sciences. Let us tell you that, his job was very hectic, and he also continued his research work at night due to his core interest in science.

Though the facilities available in the laboratory were very limited, he continued his research and published his findings in leading international journals, including 'Nature', 'The Philosophical Magazine', 'Physics Review', etc. At that time, his research was focused on the areas of vibrations and acoustics. He got an opportunity to join the University of Calcutta in as the first Palit Professor of Physics.

After 15 years at Calcutta, he became a Professor at the Indian Institute of Science at Bangalore from to and sincehe has been the Director of the Raman Institute of Research at Bangalore which was established and endowed by him only. He established the Indian Journal of Physics in where he was the editor. He also sponsored the establishment of the Indian Academy of Sciences and served as the President since its inception.

Inhe wrote an article on the theory of musical instruments for the 8th Volume of the Handbuch der Physik. He published his work on the "Molecular Diffraction of Light" in which led to his ultimate discovery of the radiation effect on February 28,and earned him the Nobel Prize in Physics in He became the first Indian to receive a Nobel Prize.

Other research carried out by Dr. Raman was on the diffraction of light by acoustic waves of ultrasonic and hypersonic frequencies and the effects produced by X-rays on infrared vibrations in crystals exposed to ordinary light. Inhe also studied the fundamental problems of crystal dynamics. His laboratory has been dealing with the structure and properties of diamonds, and the structure and optical behaviour of numerous iridescent substances like pearls, agate, opal, etc.

He was also interested in the optics of colloids, electrical and magnetic anisotropy, and the physiology of human vision.
