You're likely thinking of Sir C.V. Raman, who won the Nobel Prize in Physics in 1930 for his work on the scattering of light, known as the Raman effect.

He was indeed an Indian scientist, and his achievement was a significant moment for science in India.

However, it's important to note that there have been other Indian scientists who have won Nobel Prizes in other fields, including:

* Har Gobind Khorana (Medicine, 1968)

* Subrahmanyan Chandrasekhar (Physics, 1983)

* Amartya Sen (Economics, 1998)

* Venkatraman Ramakrishnan (Chemistry, 2009)

So, while Sir C.V. Raman is the only Indian scientist to win the Nobel Prize in Physics, there are many others who have contributed significantly to science and won Nobel Prizes in other fields.
