On 7th November 2020, to mark the 132nd birth anniversary of Nobel Laureate physicist, Sir Chandrasekhara Venkata Raman popularly known as CV Raman the official handle of the Nobel Prize committee shared a rare 24 seconds video footage of the physicist. The video was taken when he visited Stockholm in 1930 to receive one of the most prestigious awards in the world, the Nobel Prize in Physics. The 24 seconds long black-n-white video is going viral across social media platforms and has left many delighted.
90 years ago, Dr. Raman’s contribution to science from the ‘Raman Effect’ to ‘Raman lines’ and his spectacular theories on the behavior of light led him to win the Nobel Prize in Physics on December 10, 1930. Dr. Raman was awarded the prestigious prize for his work on light scattering, which came to be called the ‘Raman effect’. He was the first Asian to receive a Nobel Prize in any branch of science.
On his 132nd birthday, the Nobel Prize Committee gave tribute to him by releasing a rare video of him. Watch the video below.
The official handle of the Nobel Prize wrote on Instagram: “Raman was awarded the physics prize ‘for his work on the scattering of light and for the discovery of the effect named after him’.”

On the eve of Sir Chandrasekhara Venkata Raman’s birthday, take a look at this clip from 1930. It displays Sir Raman after he has arrived in Stockholm for the Nobel Prize Award Ceremony that was held on 10 December 1930. Raman was awarded the physics prize “for his work on the scattering of light and for the discovery of the effect named after him.” When light meets particles that are smaller than the light’s wavelength, the light spreads in different directions. This occurs, for example, when light packets – photons – encounter molecules in a gas. In 1928 Venkata Raman discovered that a small portion of the scattered light acquires other wavelengths than that of the original light. This is because some of the incoming photons’ energy can be transferred to a molecule, giving it a higher level of energy. Among other things, the phenomenon is used to analyze different types of material. Video copyright © Sveriges Television AB 2009 #NobelPrize #NobelLaureate #physics
The official Twitter handle of Nobel Prize made another post on 7th November 2020 on which they give a small definition of the Raman Effect.
They wrote on Twitter “The Raman effect is the change in the wavelength of light that occurs when a light beam is deflected by molecules. It was named after Sir Chandrasekhara Venkata Raman who was born #OnThisDay, 7 November 1888. The Raman effect is used to analyse different types of material.”
