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.

those days.

essay ‘The Molecular
Diffraction of Light’.

quanta, that is, as mass less
as particles of energy.

11. K.R.Ramanathanfinding the
phenomenon in 1923
Raman’s hunch
His direction towards finding evidence for the
corpuscular theory of light.

th
February….
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

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.
