History National Science Day 2024

National Science Day is celebrated in India every year on February 28th to commemorate the discovery of the “Raman Effect” by Sir C. V. Raman on the same date in 1928. This groundbreaking discovery earned him the Nobel Prize in Physics in 1930 and significantly impacted our understanding of light and matter interaction.

Indian Association for the Cultivation of Science, Kolkata, West Bengal; 1907–1933: Sir Chandrasekhara Venkata Raman, Tamil Brahman, Inc. Here he had studied a number of physics subjects, including the Raman Effect, which was the greatest scientific discovery in Indian history. ‘National Science Day 2024’

In 1986, the Indian government was petitioned to declare February 28th as National Science Day by the National Council for Science and Technology Communication (NCSTC). 28 February was proclaimed National Science Day in 1986 after the government approved it. February 28, 1987, was designated as the first National Science Day.

Fellowship of the Royal Society (1924), Knight Bachelor (1929), Nobel Prize in Physics (1930), Bharat Ratna (1954), Lenin Peace Prize (1957), and Fellow of the Royal Society (1924) are among the honors that CV Raman has received.

What is Raman Effect?

The Raman effect, also known as Raman scattering, is a phenomenon in physics where light scatters inelastically from molecules. This means that there is an exchange of energy between the light and the molecule, resulting in a change in the wavelength of the scattered light. ‘National Science Day 2024’

Mechanism:

  • When light interacts with a molecule, most of the light is scattered elastically, meaning its wavelength remains unchanged.
  • However, a small portion of the light interacts with the molecule’s vibrational or rotational modes, causing the molecule to absorb energy from the light or transfer energy to the light.
  • This energy exchange results in a shift in the wavelength of the scattered light.

Types of Raman Scattering:

  • Stokes Raman scattering: The molecule gains energy from the light, leading to a longer wavelength (lower energy) in the scattered light. This is the most common type of Raman scattering.
  • Anti-Stokes Raman scattering: The molecule loses energy to the light, leading to a shorter wavelength (higher energy) in the scattered light. This is less common than Stokes Raman scattering.

Applications:

The Raman effect has numerous applications in various fields, including:

  • Chemistry: Raman spectroscopy, a technique based on the Raman effect, is used to identify and analyze the chemical composition of materials.
  • Physics: Studying the Raman spectrum of a material can provide information about its structure, bonding, and vibrational modes.
  • Material science: Raman spectroscopy is used to characterize materials for various applications, such as semiconductors, pharmaceuticals, and polymers.
  • Biology: Raman spectroscopy can be used to study biological molecules and cells, providing insights into their structure and function. ‘National Science Day 2024’

Discovery:

The Raman effect was discovered by Sir C. V. Raman in 1928 and earned him the Nobel Prize in Physics in 1930. His groundbreaking discovery significantly impacted our understanding of light-matter interaction and paved the way for numerous scientific advancements.

In conclusion, the Raman effect is a crucial phenomenon in physics with diverse applications in various scientific fields. It allows us to analyze the composition and properties of materials at the molecular level, contributing significantly to scientific research and technological development.
