C V Raman
C V Raman, also known as Sir Chandrasekhara Venkata Raman, was an Indian physicist and Nobel laureate. He was born on November 7, 1888, in Tiruchirappalli, Madras Presidency, British India (now Tamil Nadu, India)
C V Raman education
CV Raman had an impressive educational background. He obtained his Bachelor’s degree in Physics from Presidency College in Chennai, India in 1904, and then went on to obtain his Master’s degree in Physics from the same college in 1907.
In 1917, Raman earned his Ph.D. degree from the University of Calcutta for his research on the scattering of light. He later held several academic positions, including professorships at the University of Calcutta and the Indian Institute of Science in Bangalore.

C V Raman Career
C V Raman had an illustrious career as a physicist and researcher. After obtaining his Ph.D. from the University of Calcutta in 1917, Raman joined the Indian Association for the Cultivation of Science as a professor of physics. He held this position until 1933 when he became the director of the Indian Institute of Science in Bangalore.
During his career, Raman also made significant contributions to the study of acoustics, optics, and magnetism. He was a member of the Royal Society of London, the National Academy of Sciences in the United States, and the Soviet Academy of Sciences.
After retiring from the Indian Institute of Science in 1948, Raman founded the Raman Research Institute in Bangalore, which is dedicated to research in physics and astronomy.
C V Raman effect
The Raman effect, also known as the Raman scattering, is a phenomenon in which a beam of light is scattered by a molecule, resulting in a change in the energy of the scattered photons. The effect was discovered by Indian physicist Chandrasekhara Venkata Raman in 1928.
The Raman effect occurs when a beam of monochromatic light is directed at a molecule and is scattered by the molecule’s electrons. The scattered light has a slightly different frequency than the incident light, resulting in a shift in the wavelength of the scattered light. This shift is characteristic of the molecule and can be used to identify its chemical composition and molecular structure.
The Raman effect is used in a variety of fields, including chemistry, physics, and biology, for the analysis of solids, liquids, and gases. It is used to identify chemical compounds, to determine the purity of a substance, and to study the vibrational modes of molecules. The Raman effect has also been used in astronomy to study the composition of distant stars and galaxies.

C V Raman Awards
CV Raman, an Indian physicist, was one of the most decorated scientists of his time. Because of which C V Raman ji received many awards and honors throughout his career. Here are some of the major awards and honors that Raman received:
Nobel Prize in Physics (1930): Raman received the Nobel Prize in Physics for his discovery of the Raman effect, which is the scattering of light by molecules.
Knight Bachelor (1929): Raman was knighted by the British government for his contributions to science.
Fellow of the Royal Society (1924): Raman was elected as a Fellow of the Royal Society, a prestigious scientific organization based in the United Kingdom.
Franklin Medal (1941): Raman was awarded the Franklin Medal by the Franklin Institute in Philadelphia for his contributions to physics.
Bharat Ratna (1954): Raman received the Bharat Ratna, India’s highest civilian award, for his contributions to science.
Lenin Peace Prize (1957): Raman was awarded the Lenin Peace Prize by the Soviet Union for his work in promoting peace and international understanding.
Padma Vibhushan (1954): Raman was awarded the Padma Vibhushan, the second-highest civilian award in India, for his contributions to science.
These awards and honors are a testament to Raman’s contributions to the field of physics and his legacy as one of India’s greatest scientists.

C V Raman’s death
Bharat Ratna CV Raman passed away on November 21, 1970, at the age of 82. He suffered a heart attack while working in his laboratory at the Raman Research Institute in Bangalore, India.
Raman had continued to work in his laboratory even in his old age and was actively involved in research until his death. He had a strong passion for science and a commitment to advancing scientific knowledge, which he had demonstrated throughout his life and career.
Raman’s contributions to the field of physics and his legacy as one of India’s greatest scientists continue to inspire future generations of scientists and researchers.
According to Raman the color of sea is blue
The blue color of the sky and the sea is due to the scattering of sunlight by the molecules in the Earth’s atmosphere and water. When sunlight enters the atmosphere, it is scattered in all directions by air molecules and other small particles. Blue light, which has a shorter wavelength and higher frequency, is scattered more than other colors, resulting in a blue sky.
Similarly, when sunlight enters the ocean, it is scattered by the water molecules and other particles in the water. Blue light is scattered more efficiently than other colors, giving the sea its blue color. The exact hue of the water depends on various factors such as the angle of the sun, the weather, the depth of the water, and the presence of other substances in the water.
While Raman did not specifically investigate the color of the sea, his work on the scattering of light provided a foundation for the understanding of the phenomenon.
