What is the CV Raman theory?
At this institute, Sir C. V. Raman discovered in 1928 that when a beam of coloured light entered a liquid, a fraction of the light scattered by that liquid was of a different color. Raman showed that the nature of this scattered light was dependent on the type of sample present.
Which year Sir CV Raman got the clear result?
C.V. Raman was an Indian physicist who won the Nobel Prize for Physics in 1930 for his discovery of what became known as the Raman effect.
What is Sir CV Raman effect?
Raman effect, change in the wavelength of light that occurs when a light beam is deflected by molecules. The phenomenon is named for Indian physicist Sir Chandrasekhara Venkata Raman, who first published observations of the effect in 1928. (Austrian physicist Adolf Smekal theoretically described the effect in 1923.
What is the discovery of CV Raman answer?
Sir C V RAMAN carried out ground-breaking work in the field of light scattering, which earned him the 1930 Nobel prize of physics . He discovered that when light traverses a transparent material, some of the deflected light changes in wavelength.
What is the contribution of the CV?
He won the 1930 Nobel Prize in Physics “for his work on the scattering of light and for the discovery of the Raman effect”. Later on the phenomenon of scattering of light was known as Raman scattering. He was the first non-white to receive a Nobel Prize for work in Science.
What did CV Raman study?
He studied the acoustics of various violin and related instruments, including Indian stringed instruments, and water splashes. He even performed what he called “Experiments with mechanically-played violins.” Raman also studied the uniqueness of Indian drums.

What is importance of Raman effect?
Raman effect helps in explaining various natural phenomenon on. like appearance of blue sky, advanced sunrise and delayed sunset, etc. It also explains the appearance of red sky during sunrise and sunset.
Why was Sir C.V. Raman awarded the Nobel Prize?
The Nobel Prize in Physics 1930 was awarded to Sir Chandrasekhara Venkata Raman “for his work on the scattering of light and for the discovery of the effect named after him.”
How does C.V. Raman explain the importance of the river Nile?
In the context of the title C.V. Raman felt the importance of water once he had a chance to stand between the line that separates the Libyan Desert and the Nile Valley of Egypt. On the other side he saw the Egyptian civilization that is greatest of all living at the valley of Nile River.
Why was Sir CV Raman awarded the Nobel Prize?
What is the contribution of C CV Raman?
C. V. Raman. Lived 1888 – 1970. C. V. Raman discovered that when light interacts with a molecule the light can donate a small amount of energy to the molecule. As a result of this, the light changes its color and the molecule vibrates.
Who is C Venkata Raman?
Biographical C handrasekhara Venkata Raman was born at Tiruchirappalli in Southern India on November 7th, 1888. His father was a lecturer in mathematics and physics so that from the first he was immersed in an academic atmosphere.
What is the contribution of Raman?
Lived 1888 – 1970. C. V. Raman discovered that when light interacts with a molecule the light can donate a small amount of energy to the molecule. As a result of this, the light changes its color and the molecule vibrates. The change of color can act as a ‘fingerprint’ for the molecule.
What is Raman spectroscopy and how does it work?
C. V. Raman discovered that when light interacts with a molecule the light can donate a small amount of energy to the molecule. As a result of this, the light changes its color and the molecule vibrates. The change of color can act as a ‘fingerprint’ for the molecule. Raman spectroscopy relies on these fingerprints.
