Who Was Chandrasekhara Venkata Raman?
Chandrasekhara Venkata Raman was a Indian physicist who was awarded the Nobel Prize in Physics in 1930 for his work on the scattering of light. He is best known for the discovery of the Raman effect, which is the inelastic scattering of a photon. This discovery led to the development of Raman spectroscopy, a technique used to study the vibrational, rotational, and other low-frequency modes in a system.
Chandrasekhara Venkata Raman was born on November 7, 1888, in the town of Tiruchirapalli in Tamil Nadu, India. He was the second of eight children born to Chandrasekhar Iyer and Parvati Ammal. His father was a lecturer in mathematics and physics at the local college, and his mother was a housewife.
Raman received his early education at the Loyola College in Madras. He excelled in his studies, particularly in physics and mathematics, and received a scholarship to study at the Presidency College in Madras. After completing his Bachelor's degree in physics in 1907, he joined the University of Madras as a research student.
In 1909, Raman received his Master's degree in physics, and in the same year, he was appointed as an assistant professor at the University of Madras. He taught at the university for a few years before being appointed as a professor of physics at the Indian Association for the Cultivation of Science in Kolkata.
Raman married Lokasundari Ammal in 1907, and the couple had two children. Raman was deeply dedicated to his work and spent long hours in his laboratory, often working late into the night. He was also a devoted husband and father, and took great pride in his family. Despite his busy schedule, he found time to play with his children and took them on outings to the beach and park.
Main Discoveries and Awards
Chandrasekhara Venkata Raman is best known for the discovery of the Raman effect, which led to the development of Raman spectroscopy, a technique used to study the vibrational, rotational, and other low-frequency modes in a system.
The Raman effect was discovered in 1928, when Raman and his team of researchers were studying the scattering of light by different substances. They found that when light is shone on a substance, some of the light is absorbed by the substance and some is scattered..
Raman's discovery was a major breakthrough in the field of physics and had significant implications for the understanding of the nature of light, which has helped developments in a wide range of fields, including chemistry, biology, material science, and medicine.
In recognition of his work on the Raman effect, Raman was awarded the Nobel Prize in Physics in 1930. He was the first Indian to receive this prestigious award, and his discovery remains one of the most significant contributions to the field of physics.
Raman also made significant contributions to the fields of optics and acoustics. He is also credited with the development of the theory of resonance, which explains the phenomenon of sound absorption and transmission in musical instruments. He received many awards and honours for his scientific contributions, including the Nobel Prize, the Order of the British Empire, and the Order of Merit.
What Is the Raman Effect?
The Raman effect was discovered in 1928 while studying the scattering of light by different substances. They found that when light is shone on a substance, some of the light is absorbed by the substance and some is scattered. The scattered light has a different frequency than the incident light.
The discovery of the Raman effect was a major breakthrough in the field of physics and had significant implications for the understanding of the nature of light. It also paved the way for the development of new technologies, such as Raman spectroscopy, which is used in a wide range of fields.
In addition to his scientific pursuits, Raman was also an avid music lover and played the veena, a stringed instrument, in his free time. He was also an avid reader and enjoyed reading books on a wide range of topics, including science, literature, and history.
Raman was highly respected in the scientific community and was known for his integrity and dedication to his work. He received many awards and honors for his scientific contributions, including the Nobel Prize, the Order of the British Empire, and the Order of Merit.
Chandrasekhara Venkata Raman died on November 21, 1970, at the age of 82. He had been suffering from heart and kidney problems for some time and was hospitalized a few days before his death.
Raman's death was widely mourned in India and around the world, and he was remembered as a brilliant scientist and a pioneer in the field of physics.
