He continued to contribute to the field of science and technology throughout his life, and his work has inspired countless scientists and researchers worldwide.

In recognition of his contributions to science and technology, the Indian government declared 28th February as National Science Day in 1986, to commemorate the discovery of the Raman Effect. National Science Day is celebrated across India to promote scientific temper and to create awareness about the importance of science and its contributions to society.

In conclusion, CV Raman's discovery of the Raman Effect is a significant milestone in the history of science, and his contributions have been recognized globally. National Science Day is celebrated in India to commemorate his work and to inspire future generations to pursue scientific research and innovation.




CV Raman was a renowned Indian physicist who is widely recognized for his contribution to the field of optics and spectroscopy. He was born on November 7, 1888, in the city of Trichy in Tamil Nadu, India. In 1930, he made a groundbreaking discovery, which is now known as the "Raman Effect." The Raman Effect is the scattering of light by molecules, which helped scientists to understand the composition and structure of matter at the molecular level.

In recognition of CV Raman's contribution to the field of science, the Indian government declared his birthday, 28th February, as National Science Day in 1986. This day is celebrated in India every year to commemorate Raman's discovery of the Raman Effect.

National Science Day is an occasion for scientists, students, and researchers to reflect on the importance of science and its role in society. It is also an opportunity to promote scientific temper and to encourage young people to take up careers in science and research.

On this day, various scientific institutions, schools, and colleges organize events such as seminars, workshops, exhibitions, and science fairs to showcase the latest developments in science and technology. These events are aimed at inspiring the younger generation to take an interest in science and to encourage them to pursue careers in this field.

In conclusion, CV Raman's contribution to the field of science is immense, and National Science Day is a fitting tribute to his legacy. The day serves as a reminder of the importance of science and its role in society and provides a platform for promoting scientific temper and encouraging young people to pursue careers in science and research.




C.V. Raman, also known as Sir Chandrasekhara Venkata Raman, was an Indian physicist who made significant contributions to the field of optics and spectroscopy. He was born on November 7, 1888, in Tiruchirappalli, India, and passed away on November 21, 1970, in Bangalore, India.

One of Raman's most significant achievements was the discovery of the Raman effect, which is the inelastic scattering of light by molecules, atoms, and other particles. This discovery was a groundbreaking achievement in the field of physics and earned Raman the Nobel Prize in Physics in 1930.

In honor of Raman's contributions to science, the Government of India designated his birthday, November 7, as National Science Day in 1986. This day is celebrated every year to commemorate Raman's discovery and to promote science education and research in India.

National Science Day celebrations typically include science exhibitions, science fairs, lectures, and other events aimed at raising awareness of the importance of science and its role in society. The day also serves as an opportunity to inspire young people to pursue careers in science and to encourage scientific research and innovation in India.




National Science Day is celebrated in India on February 28th each year to commemorate the discovery of the Raman Effect by the renowned Indian physicist Sir Chandrasekhara Venkata Raman, also known as CV Raman.

CV Raman was born in 1888 in the southern Indian state of Tamil Nadu. He made numerous contributions to the field of physics during his lifetime, but his most significant discovery was the Raman Effect. In 1928, while studying the scattering of light by molecules, he discovered that when light passes through a material, a small fraction of it is scattered in all directions. Some of this scattered light is shifted to a slightly longer or shorter wavelength than the original light, a phenomenon now known as the Raman Effect.

This discovery was groundbreaking and had far-reaching implications for the field of physics. It provided a new way of looking at the structure of matter and helped to establish the quantum mechanical theory of light-matter interactions.

In recognition of his contribution to science, CV Raman was awarded the Nobel Prize in Physics in 1930, becoming the first Indian to receive this prestigious honor. His work has had a significant impact on physics and other fields of science, and he is remembered as one of the greatest scientists in Indian history.

National Science Day is celebrated in India to honor CV Raman's contribution to science and to encourage scientific temper in the country. On this day, various activities and events are organized across the country to promote science education and research. It serves as a reminder of the importance of scientific research and its impact on society.

CV Raman was born on November 7, 1888, in the city of Tiruchirapalli in Tamil Nadu, India. He received his education from the University of Madras and later pursued his research work at the Indian Association for the Cultivation of Science in Kolkata.

In 1928, while working at the Indian Association for the Cultivation of Science, Raman discovered the Raman effect, which is a phenomenon that occurs when a beam of light passes through a material and is scattered in different directions, with some of the scattered light having a different frequency than the original beam. This discovery laid the foundation for the field of Raman spectroscopy, which is widely used in many scientific fields to study the molecular structure of materials.

For his discovery, Raman was awarded the Nobel Prize in Physics in 1930, becoming the first Asian and the first Indian to receive the prestigious award. Raman also made significant contributions to the study of optics, acoustics, and crystal physics.

National Science Day is celebrated in India to honor Raman's contribution to science and to encourage scientific temper in the country. On this day, various science-related activities and events are organized across the country to promote science education and research.
