National Science Day celebrates C V Raman’s discovery of the Raman Effect and promotes scientific thinking across India every year
New Delhi: India celebrates National Science Day every year on February 28 to remember the discovery of the Raman Effect by C. V. Raman in 1928. This day recognises one of the most important scientific achievements in India’s history and highlights the importance of science and technology in the country’s growth.
C. V. Raman discovered how light changes when it passes through a transparent material. This discovery later became known as the Raman Effect. Because of this important work, he received the Nobel Prize in Physics in 1930, becoming one of the first Indians to win a Nobel Prize in science.
How This Day Started
Although Raman made his discovery in 1928, India officially began celebrating National Science Day in 1987. In 1986, the National Council for Science and Technology Communication suggested that the Government of India declare February 28 as National Science Day. The aim was to encourage scientific thinking and increase awareness about the value of research.
Since then, schools, colleges, universities and research institutions across the country have marked the day with various educational and awareness activities.
What Is the Raman Effect?
The Raman Effect explains what happens when light passes through a transparent substance. Most of the light continues without any change. However, a small part of the light scatters and changes its wavelength.
This change happens because the light exchanges energy with the molecules of the material it passes through. Even though the change is very small, it helps scientists understand the structure and properties of different substances.
Raman’s discovery later led to the development of Raman spectroscopy, a scientific method that allows researchers to study materials without damaging them.

Why the Raman Effect Is Important
The Raman Effect has many important uses in science and technology today.
In Material and Chemical Research
Scientists use Raman spectroscopy to identify the molecular structure of substances. It helps researchers study materials accurately in laboratories.
In Medicine and Pharmaceuticals
Researchers use this technique to study tissues and detect diseases at an early stage. It supports cancer research and helps scientists observe changes in cells.
In Environmental and Forensic Studies
The Raman Effect helps identify unknown substances by analysing their molecular structure. This is useful in environmental monitoring and criminal investigations.
In Advanced Technology
The discovery also supports developments in nanotechnology, semiconductor research and other advanced scientific fields.
Theme 2026
Each year, the Government of India announces a theme for National Science Day to focus on an important scientific goal.
For 2026, the theme announced by the Department of Science and Technology is:
“Women in Science: Catalysing Viksit Bharat.”
This theme highlights the importance of women’s participation in science. It encourages more women to take leadership roles in research and innovation. The theme also supports the vision of building a “Viksit Bharat,” meaning a developed India, through equal opportunities in science and technology.
How India Celebrates
National Science Day is celebrated across the country in many ways.
School and College Activities
Educational institutions organise science exhibitions, quizzes, debates, speeches and poster-making competitions. These activities help students understand science in an interesting way.
Seminars and Lectures
Scientists and experts give talks about new discoveries and explain how science helps solve real-life problems.
Science Demonstrations
Institutions organise live experiments and displays to explain scientific concepts, including the Raman Effect, in simple language.
National-Level Programme
The Department of Science and Technology holds a main celebration at Vigyan Bhawan, where leaders and scientists discuss achievements and launch new initiatives.
Public Awareness Programmes
Science centres and planetariums conduct workshops and special programmes to involve people of all age groups.
Why It Is Important
National Science Day plays an important role in society.
Encouraging Scientific Thinking
The day promotes logical thinking and evidence-based decision-making in everyday life.
Honouring Indian Scientists
It recognises the achievements of scientists like C. V. Raman and highlights India’s contribution to global science.
Inspiring Young Students
By celebrating science in schools and communities, the day encourages young people to choose careers in science and research.
Supporting National Development
Science helps improve healthcare, agriculture, environment and the economy. National Science Day reminds people how scientific progress improves daily life.

The Legacy of C. V. Raman
C. V. Raman was born in 1888 in Tamil Nadu. He showed great interest and talent in physics from a young age. Despite limited resources during British rule, he carried out important research that gained international recognition.
His discovery of the Raman Effect changed the way scientists study light and matter. Even today, researchers around the world use his method in laboratories and scientific studies.
Looking Ahead
National Science Day 2026 is not only about remembering a historic discovery. It is also about encouraging innovation, promoting inclusion and strengthening India’s future through science.
By celebrating the Raman Effect and focusing on the role of women in science, India continues to move towards becoming a developed and knowledge-driven nation.
On February 28, the country honours a proud scientific legacy and inspires the next generation to explore, discover and innovate for a better future.
