National Science Day is celebrated annually in India on February 28th to commemorate Indian physicist Sir Chandrasekhara Venkata Raman's discovery of the Raman effect in 1928. For this achievement, Raman was awarded the Nobel Prize in Physics in 1930, bringing great success to the field of science in India. The Raman effect describes the change in wavelength of a small fraction of light passing through a transparent sample, with most light unchanged but a small part shifted to different wavelengths.

3. National Science Day Is Celebrated All
Over India With Great Enthusiasm On 28th
Of February Every Year In Order To
Commemorate The Invention Of The
Raman Effect In India By The Indian
Physicist, Sir Chandrasekhara Venkata
Raman.
For His Great Success In The Field Of
Science In India, Chandrasekhara Venkata
Raman Was Awarded And Honoured With
The Nobel Prize In The Physics In The Year
1930.

4. RAMAN EFFECT, Change in the
wavelength of light that occurs when a light
beam is deflected by molecules. When a
beam of light traverses a dust-free,
transparent sample of a chemical
compound, a small fraction of the light
emerges in directions other than that of the
incident (incoming) beam. Most of this
scattered light is of unchanged wavelength.
A small part, however, has wavelengths
different from that of the incident light; its
presence is a result of the raman effect.
