National Science Day
National Science Day is observed in India every year on February 28 to commemorate Dr. C. V. Raman's ground breaking discovery of the 'Raman Effect' on that day in 1928. This significant achievement earned him the Nobel Prize for physics in 1930, making him the first Asian to receive this honour. Dr. Raman's ability to find science in ordinary things revitalised scientific curiosity in India.
The celebration of National Science Day shows the importance of science in our lives. Activities such as speeches, radio programs, TV shows, Science movies, exhibitions, debates, quiz competitions and teachers are organized in schools and colleges to highlight the role of science in creating better systems and improving our understanding of the living world.
Dr. Raman's advice - "Ask the right questions, and Nature will open the doors to her secrets" - Serves as an inspiration for future scientists. As we celebrate this special day, let us foster a scientific mind-set and encourage curiosity, striving to be the future discoveries of new scientific wonders.
Understanding Dr. C. V. Raman's Discovery for National Science Day
National Science Day is celebrated in India on February 28th each year. This day honours a very important scientific achievement by an Indian scientist, Dr. C. V. Raman.
Key Information from the Text:
- The celebration commemorates the discovery of the 'Raman Effect' by Dr. C. V. Raman.
- This discovery happened on February 28, 1928.
- Dr. C. V. Raman received the Nobel Prize in Physics in 1930 for this work.
- He was the first Asian person to win a Nobel Prize in Physics.
- His ability to see science in everyday things inspired many in India.
What Did Dr. C. V. Raman Discover?
The comprehension text clearly states that Dr. C. V. Raman's "ground breaking discovery" was the 'Raman Effect'. This discovery is the reason National Science Day is observed on February 28th.
Looking at the options provided:
- Raman Defect
- Raman Effect
- Raman Affect
- Raman Reflect
The correct discovery, as mentioned in the text and celebrated on National Science Day, is the Raman Effect.
Significance of the Raman Effect
The 'Raman Effect' is a phenomenon in physics related to the scattering of light. When light passes through a transparent material, most of the light is scattered unchanged, but a small fraction of the light is scattered in such a way that its wavelength changes. This change in wavelength is called the Raman Effect.
Dr. Raman's discovery not only brought international recognition to India but also sparked a spirit of scientific inquiry among students and researchers. His advice, "Ask the right questions, and Nature will open the doors to her secrets," continues to inspire budding scientists.
