- DictionaryRaman effect/ˈrɑːmən/
noun
- 1. a change of wavelength exhibited by some of the radiation scattered in a medium. The effect is specific to the molecules which cause it, and so can be used in spectroscopic analysis.

Raman scattering is defined as the scattering of photons by excited molecules at higher energy levels. It is also known as the Raman effect. The photons are inelastically scattered, which means that the kinetic energy of an incident particle is either lost or increased and is composed of Stokes and anti-Stokes portions.
Feb 27, 2021 · Sir C V Raman – a man of vigour, intensity and childlike curiosity! February 28 in India is celebrated as National Science Day because of the discovery of Raman Effect by Sir C V Raman on that day in 1928. He was the first Indian, Asian, and Non-White person to win the Nobel Prize for Physics in 1930 for his pioneering work on scattering of ...
Nov 21, 2017 · This effect proved the quantum nature of light and had huge value at that time. The Raman Spectroscopy was based on this phenomenon. Consequently, February 28 is celebrated as National Science Day in India since 1987 annually in honour of this discovery. For this discovery, Raman was awarded the Nobel Prize in Physics in the year 1930.
Nov 14, 2018 · Raman was conferred the country’s highest civilian award, the Bharat Ratna in 1954 due to his impressive work in the field of Science. Today, we all celebrate February 28th as the National Science Day, honouring his discovery of the Raman Effect. Raman believed that if you ask the right questions ‘nature will open the doors to her secrets’.
The correct option is C. c) Both 1 and 2. India celebrates its National Science Day every year on February 28 to mark Dr. C.V. Raman’s discovery of the scattering of light, also known as the Raman Effect.
Nov 7, 2022 · Raman was intrigued by music and sound. He studied the vibrations and acoustics of many instruments like the violin, drums, and even published papers on them. Raman had an extensive collection of rocks, fossils and minerals from all over the world to study scattered light structures that produce colours. He always carried a small spectroscope ...
Raman scattering, often known as the Raman effect, is the inelastic scattering of photons from an atom or molecule. The renowned Indian physicist C. V. Raman first identified this effect in 1928. The majority of photons, which have the same energy and wavelength as the incident photons, are often elastically dispersed from an atom or a molecule.
Statement 1 is correct: Raman effect is the change in the wavelength of light on deflection from molecules of the medium. When a beam of light traverses a dust-free, transparent sample of a chemical compound, a small fraction of the light gets deflected (scattered) in directions other than that of the incident beam.
This phenomenon is termed a scattering of light. The intensity of scattered light depends on the size of the particles and the wavelength of the light. Shorter wavelength and high-frequency scatter more due to the waviness of the line and its intersection with a particle. The wavier the line, the more the chance it intersects with a particle.
Feb 27, 2021 · Sir C V Raman – a man of vigour, intensity and childlike curiosity! February 28 in India is celebrated as National Science Day because of the discovery of Raman Effect by Sir C... The impact of Sir Chandrasekhara Venkata Raman or CV Raman on our country and the world of science is well-known.
