India has seen the rise of many scientists and intelligent minds that has gone far beyond their comfort zone and gifted the fellow citizen’s remarkable works and inventions. In Indian history, Bharat Ratna, Dr C.V Raman is considered to one of the most prominent names.
Dr C.V Raman or Sir Chandrasekhara Venkata Raman was born in Chennai, formerly known as Madras in the year 1888. His ground breaking contribution in the world of physics fetched him the Nobel Prize for Physics during the year 1930. The discovery made by this scientist is popularly known to the entire world as the “Raman effect” or the “Raman scattering”. As per his discovery light while traversing a material transparent in nature experiences a change in wavelength in some of the light waves.
Right from his childhood the sparks of his intelligent mind was been noticed. Coming from his father who was a Physics teacher, C.V Raman was a very well performing talented student in school.
On passing his matriculation examination during twelve years of age he desired to go for higher studies outside India. But, a British surgeon advised him not to and hence, he stayed back to complete his graduation from the Presidency college in Madras.
By undergoing graduation and then masters in Physics this individual made many important researches in this field. His research paper related to the diffraction of light even got published and earned great recognition.
During the year 1921, while he was on a sea voyage towards Europe on the Mediterranean Sea his observant eyes caught the glimpse of the blue color of the glaciers.
Although a visual treat his mind went deeper and he kept wondering about the reason of this blue color on ice. On returning from his trip and after conducting a series of various experiments he presented to the world the reason of the blue colour we see in oceans and sky.
It was this event which was a precursor to the world famous “Raman effect”. It was on an evening during year 1927 December month, when he received news that Professor Compton founded X-rays and won Nobel Prize for this amazing invention. The thought made Dr Raman debate within him that if Compton Effect is applied for X-rays then the same can even be applied for light. |
To solidify his speculation, Dr Raman used monochromatic light from an arc which had mercury and made it pass through a material which was transparent on a spectrograph as it will record the spectrum of light. He noticed the occurrence of new lines on the spectrum and termed them as “Raman Lines”. This discovery gifted him the prestigious Nobel Prize in the year 1930. This discovery helped scientists understand the structure of molecules in chemical compounds.
It was during the year 1934 when Dr Raman set up his scientific research unit in Bangalore known as the Raman Research Institute. Until he took his last breath on 21st of November, 1970 he immersed himself into the world of scientific research and works.
From time to time the resolve of Indian scientists has been proved to the entire scientific world. Salute this legendary scientist for his great invention which helped the world understand and perceive things in a different way.
