Every year on 28th February, we commemorate National Science Day to honor the contributions that scientists have made to the growth and prosperity of our nation. The Raman Effect, a major finding in the science of spectroscopy, was made on this day in the year 1928 by the eminent Indian scientist Dr Chandrasekhara Venkata Raman, famously known as CV Raman. In 1930, the Nobel Prize in Physics was bestowed upon Sir CV Raman for his contributions to the field.
Light wavelength shifts due to molecular deflection are known as the Raman Effect or Raman Scattering. A small percentage of the light passing through a transparent sample of a chemical compound will emerge going in the opposite direction of the incoming beam. Some of that light has a wavelength that is different from the light that was originally shining on the object. As a result of the Raman Effect, a natural phenomenon.
CV Raman earned his master's degree at the age of 19, by which time he had already established himself as one of the most prominent scientists in India and around the world. In 1921, he took his first trip to the United Kingdom. When traveling back, Raman took note of the Mediterranean Sea's striking blue color and wondered why it wasn't green. He hypothesized that light scattering by water molecules was responsible for the sea's blue color, prompting an additional study of light scattering.

The rituals that surround the event
To celebrate National Science Day and encourage more kids to pursue careers in science, events are held all around the country. In addition, in February 1987, the Department of Science and Technology (DST) established the National Awards for Science Popularization to honor individuals for their efforts to increase the public's understanding of scientific topics.
The National Science Day is supported and coordinated by the National Council for Science and Technology Communication (NCSTC), which is part of the Department of Science and Technology (DST). In addition, the DST instituted the National Awards for Science Popularization in February 1987 to honor scientists for their exemplary public outreach. There are six different types of awards given out on National Science Day.
