Sir C.V. Raman was chosen as the subject of the biography due to his extraordinary abilities and curiosity that led to his Nobel Prize-winning discovery. He was born in 1888 in India and showed academic excellence from a young age, obtaining degrees in physics. His curiosity about the color of the sea led to his discovery of the Raman effect in 1922, for which he received the 1930 Nobel Prize in Physics. Later in his career, he devoted himself to setting up the Raman Research Institute in Bangalore and serving as the head of the Indian Academy of Science until his death in 1970.

2. C.V.Raman
The Nobel laureate in physics

3. Reason to choose sir C.V. Raman
Sir CV Raman was the man of extraordinary
ability. At the age of 15 he had a degree with
a gold medal in physics. By the time he was
19 he had MA. In addition to being brilliant,
he was curious about the world around him.
We saw his curiosity about the color of the
sea that led to the discovery of Raman Effect
which gained him the 1930 Nobel Prize in
Physics. Also his good thoughts made me
choose him.

10. Raman’s discovery….
 Water molecule could scatter
light just like air molecules.
 His thought was a radical in
those days.
 In 1922 he wrote a brilliant
essay ‘The Molecular
Diffraction of Light’.
 He said light may exist in
quanta, that is, as mass less
as particles of energy.

11. K.R.Ramanathan finding the
phenomenon in 1923

corpuscular theory of light.

 The famous Raman effect….the light can undergo a
scattering through a liquid resulting in a change in
its frequency….
 The date is celebrated as National Science Day
 Received Nobel Prize for Physics in 1930

the memory of Raman.

14. Takeaways Sir C.V. Raman
We people think that to become successful in life we
need good college and cities but he proved that
nothing of that matters, what matters is the hard
work and struggle with which you study.
Also he didn't wanted to do the Philosophy degree
but he did that because he had the free books of his
elder brother, that also teaches us that we
sometimes need to change our choices depending
over situations.
