India observed National Science Day 2026 on 28 February 2026 to commemorate the discovery of the Raman Effect by C. V. Raman. For this groundbreaking discovery, Sir C.V. Raman was awarded the Nobel Prize in Physics in 1930, becoming the first Asian to receive a Nobel Prize in the sciences.
Theme of National Science Day 2026
“Women in Science: Catalysing Viksit Bharat”
The 2026 theme highlighted:
- The contribution of women scientists and innovators.
- Their role in building a developed India (Viksit Bharat).
- Gender inclusion in research, technology, and STEM fields.
The theme aligns with global initiatives such as the International Day of Women and Girls in Science, promoting gender equality and increased participation of women in scientific research.

| Particular | Details |
| Discovery | Raman Effect |
| Date of Discovery | 28 February 1928 |
| First Observed as National Science Day | 1987 |
| Declared by | Government of India (1986) |
The day was declared by the Government of India in 1986 and first celebrated in 1987 to honour the discovery of the Raman Effect. C.V. Raman was First Asian Nobel Laureate in Science.
What is the Raman Effect?
The Raman Effect explains how:
- Light changes its wavelength when it passes through a transparent medium.
- A small fraction of light is scattered at different wavelengths.
- This scattering provides information about the molecular structure of substances.
Scientific Importance
- Foundation of Raman Spectroscopy.
- The Raman Effect advanced understanding of light scattering and molecular physics.
- Widely used in: Physics, Chemistry, Medical diagnostics, Material science, Forensic science, Pharmaceutical research
Broader Objectives of National Science Day
- Promote scientific temper among citizens (as envisioned under Article 51A(h) of the Constitution).
- Encourage youth to pursue careers in STEM.
- Recognise achievements of Indian scientists.
- Strengthen the role of science in national development.
- Reduce gender gaps in STEM fields.
National Celebrations in 2026
Across India, institutions organised:
- Science exhibitions
- Workshops
- Debates and quiz competitions
- Public lectures
- STEM outreach programmes
- Awareness drives promoting women’s participation in science
Schools, colleges, research institutes, and science centres actively participated.
