DR. CHANDRASEKHARA
VENKATA RAMAN (C.V.
RAMAN)
INTRODUCTION
Dr. Chandrasekhara Venkata Raman, widely known as
C.V. Raman , was one of India's greatest physicists. His
pioneering work in the field of light scattering led to
the discovery of the Raman Effect , which earned him
the Nobel Prize in Physics in 1930. His contributions to
science and education have made a lasting impact on
the world.
CAREER AND RESEARCH
Early Career
In 1907 , he cleared the Indian Finance Service (IFS) exam and was posted
in Kolkata.
While working at the Indian Finance Department , he continued research
at the Indian Association for the Cultivation of Science (IACS).
His research on light, acoustics, and optics gained international
recognition.
CAREER AND RESEARCH
Discovery of the Raman Effect
In 1921 , during a trip to Europe, he was fascinated by the color of the sea and sky,
which led him to research light scattering.
On February 28, 1928 , along with his student K.S. Krishnan , he discovered the
Raman Effect , which explained the scattering of light and its interaction with
molecules.
This discovery proved that light changes its wavelength when passing through a
transparent medium.
February 28 is now celebrated as National Science Day in India in his honor.
AWARDS AND RECOGNITIONS
Nobel Prize in Physics (1930) – First Indian and first Asian to
win a Nobel in science.
Knight Bachelor (1929) by the British Government.
Bharat Ratna (1954) – India’s highest civilian award.
Lenin Peace Prize (1957).
Fellow of the Royal Society (1924).
CONTRIBUTIONS TO SCIENCE
1. Raman Effect
The discovery revolutionized spectroscopy and led to the development of
Raman Spectroscopy , a key tool in chemistry and physics.
This effect is used in chemical analysis, pharmaceuticals, forensic
science, and nanotechnology.
CONTRIBUTIONS TO SCIENCE
3. Work in Optics and Crystallography
Researched X-ray diffraction and crystal structures.
Made important contributions to light scattering and
color perception.
CONTRIBUTIONS TO SCIENCE
- 4. Role in Science and Education
Mentored many young scientists, including G.N.
Ramachandran.
Strong advocate for scientific research and self-
reliance in India.
CONCLUSION
C.V. Raman’s contributions to science, especially in the
field of light scattering, have had a profound impact on
modern physics. His relentless dedication to research,
education, and self-reliance makes him one of the
greatest scientists in history. His work continues to
inspire millions of students and researchers around the
world.
