He is the first Asian to receive a Nobel Prize in Physics for his work on the scattering of light and the discovery of the effect named after him in 1930. Birth: Sir C.V. Raman, was born to a Tamil family on 7th November 1888. His father was Chandrasekhara Ramanathan Iyer, and his mother Parvathi Ammal. Since childhood, he was very keen on pursuing science and later became one of the eminent scientists of India. Childhood: Since his early childhood, C. V. Raman has been a bright and intelligent student. He received a scholarship at the age of 11 and completed his matric and 12th class at the age of 13. Raman was raised in an academic background as the son of a mathematics and physics lecturer. He was a great student throughout his academic career and was passionate about re...

Bengaluru: India celebrates National Science Day on 28 February every year in honour of physicist C.V. Raman’s discovery of the Raman Effect, which gave Asia its first Raman and his student-collaborator K.S. Krishnan made the discovery of the phenomenon in 1928. But Raman’s Nobel win came two years later. It was the As India celebrates another year of the physicist’s discovery, ThePrint details the science behind it. The Raman Effect In 1921, C.V. Raman was on a trip to Europe when he noticed the striking blue colour of some icebergs and the Mediterranean Sea. He was inspired to want to understand the reason behind the phenomenon. He conducted experiments with transparent blocks of ice and light from a mercury arc lamp. He recorded the spectra from shining the light through ice and detected what would come to be known as the Raman Lines, caused by 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. When a beam of light travels through a dust-free, transparent chemical, a small fraction of the light emerges in directions other than where it should. Light consists of particles called photons, whose energy is directly proportional to the frequency with which they travel. When they strike molecules in a medium at high speeds, they bounce back and scatter in different directions depending on the angle with which they hit the molecu...

He has made many android apps and websites with several technical manuals and given countless lectures, workshops, and seminars throughout his 15-year-old age career. The journey started when 13-year-old Nitesh got his first laptop when he topped his 8th class. He started experimenting and googling things […] I am the master of my failure… If I never fail, how will I ever learn? Speaking about Indian Great personalities and not mentioning DR.CV Raman then it’s impossible. C.V Raman was the First Indian to win the Nobel Prize for Physics. He was a mentor and an avid lover of nature. EARLY LIFE: C.V Raman was born on 7 November 1888 in the city of Tiruchirappalli of Tamil Nadu. His full name was Chandrasekhara Venkata Raman. At at an early age Raman moved to the city Visakhapatnam. From a very young age, the education of CV Raman has been exceptional. His hobby was to read varieties of books. And Science as a subject always fascinated the young Raman. CV Raman was a brilliant student right from his childhood and always stood first in his field of education.At the age of 11, he completed his matriculation. At the age of 13, he passed his F.A Examination (equivalent to today’s intermediate exam PUCPDC and +2) and at the age of 14, Raman began his bachelor’s degree at the Presidency College in 1903. He did B.A and M.A in Physics and his university life, he had displayed exemplary brilliance in scientific investigations. ...

Nobel Laureate and Honorary Member Chandrasekhara Venkata Raman was born in 1888 in southern India. He received a B.S. in 1904 and an M.S. in 1907 from Presidency College, Madras. Because scientific research was almost completely neglected in India, Raman did not begin his career in physics. Instead, he took a civil service post in the finance department in Calcutta in 1907, and continued his scientific work in his spare time. Over the next decade, he published some 30 papers in Nature, Philosophical Magazine and Physical Review—which helped to make his name familiar outside of India. In 1917, he was offered a physics appointment at Calcutta University. This marked the beginning of a very productive time in Raman’s life, which he termed his “golden era.” It extended from 1917 until 1933 and included multidisciplinary research in optics, acoustics and other branches of physics. In 1918, Raman published the first in a series of experiments on the molecular diffraction of light, which led to his 1928 discovery of the Raman Effect. Using a very simple apparatus, he found that, when a beam of monochromatic light is scattered by a transparent medium, the scattered light has weak components of changed frequency, with the shift characteristic of the substance causing the scattering. Other scientists quickly verified his published results. Other scientific investigations included his experimental and theoretical studies on the diffraction of light by acoustic waves of ultrasonic an...

Can you imagine what it might be like to be the first person from your country to win the Nobel Prize? What about the first person from your race or even continent? If you can, you might have some idea of what life was like for C.V. Raman! Born in 1888 into an academically minded family in India, Chandrasekhara Venkata Raman would go on to surpass the achievements of his professor father by becoming the first Asian to receive the Nobel Prize in physics. The second of eight children, C.V. was the son of a college professor. His father, Chandrasekaran, taught math, geography, and physics. He encouraged all of his children to excel in academics, and young C.V. finished his traditional schooling at the age of eleven. Raman would complete both his bachelor's and master's degrees in physics before he turned 20. His early graduations were quite an achievement, even by today's standards. Raman would discover what is known today as the Raman effect, which helps to explain why certain molecules cause waves of radiation to scatter differently than other molecules. While traveling to Europe in the early 1920s, C.V. noticed that glaciers had a blue color and was intrigued. He wanted to find out what the cause of the blue coloration was and would go on to analyze how water molecules scatter light in an attempt to explain the situation. These experiments would lead him to be interested in how other materials might interact with light, or other types of electromagnetic waves. At the time,...

Raman spectroscopy is a chemical analysis technique which involves illuminating a substance with a laser and analyzing the light that is scattered off the surface of the substance. The scattered light can provide a lot of information about the substance and its structure, and can be used to identify, characterize, and quantify many chemical components. When light is scattered off a sample there are two possible outcomes: (1) Elastic scattering, also known as Rayleigh scattering, occurs when the scattered light has the same energy as the light that initially struck the sample. This means that the elastically scattered light will be the same frequency, wavelength, and color as the original beam of light. (2) Inelastic scattering, or Raman scattering, occurs when the scattered light has a different energy than the light that initially struck the sample. This means the inelastically scattered light will have a different frequency, wavelength, and color than the original beam of light. The answer has to do with the constant motion of atoms in a molecule, which makes the bonds in atoms kind of like springs that are constantly vibrating in different directions. These molecular vibrations happen at specific frequencies which are unique to the molecule and type of bond. An popular and easy example for such a spring is molecular oxygen (O 2) or nitrogen (N 2). Imagine each moleccule as two hard spheres connectect by spring of a certain strengths and therefore specific vibrational fr...
