C.V. Raman Biography & Raman Effect Explained for Kids

Sir Chandrasekhara Venkata Raman, popularly known as C.V. Raman, remains one of the most influential scientists in Indian history. His groundbreaking discovery of the Raman Effect not only earned him a Nobel Prize in Physics in 1930 but also positioned India on the global scientific map. His journey from a child prodigy in a Tamil Brahmin household to becoming a globally recognized physicist is one of passion, intellect, and relentless curiosity.

Before we dive into the fascinating life of this iconic scientist, here is something equally exciting for young learners.

Early Life and Education of C.V. Raman

Born on 7th November 1888 in Tiruchirapalli, Tamil Nadu, C.V. Raman belonged to a family deeply rooted in academics and tradition. He was one of eight siblings in a Hindu Tamil Brahmin family. From an early age, Raman exhibited an exceptional aptitude for learning, often astounding teachers and elders with his intellect. His father, a lecturer in mathematics and physics, greatly influenced his academic inclinations.

Raman completed his secondary education at the age of 11 and his higher secondary at just 13. By the age of 16, he had already graduated with a Bachelor’s degree in Physics with honours, topping his class. Even before completing his graduation, Raman published his first scientific research paper on the ‘diffraction of light’, indicating his early passion for optics and light behavior. His academic trajectory was steep and impressive, culminating in a Master’s degree before he turned 19.

Early Career: Bridging Bureaucracy and Science

Despite his scientific brilliance, Raman initially pursued a government job and was appointed as Assistant Accountant General in the Indian Finance Service, stationed in Calcutta. This might seem like a detour from science, but Calcutta was home to the Indian Association for the Cultivation of Science (IACS), India’s first research institute. Raman spent his evenings at IACS, conducting experiments on acoustics and optics. These amateur yet passionate investigations soon caught the attention of the scientific world.

His research at IACS earned him growing recognition and eventually led to his appointment as the ‘Palit Professor’ in the Physics Department of the University of Calcutta. Here, Raman got the opportunity to conduct full-time research and mentor budding scientists, including his notable associate, K. S. Krishnan.

The Mediterranean Spark: The Birth of the Raman Effect

In 1921, Raman had his first opportunity to visit Europe. While sailing across the Mediterranean Sea, he noticed the deep blue colour of the water and questioned the existing explanation that Rayleigh-scattered light caused the phenomenon. Driven by curiosity and a desire to offer a better explanation, he began experiments on light scattering upon his return to India.

Meanwhile, in 1923, Arthur Compton’s discovery (now called the Compton Effect) proved that X-rays could behave like particles. This revolutionary finding in quantum physics motivated Raman to explore if visible light exhibited similar properties. Working closely with K. S. Krishnan, Raman embarked on a series of experiments that would ultimately change the understanding of light forever.

The Discovery of the Raman Effect

In 1927, after years of investigation, Raman and Krishnan discovered a phenomenon where light passing through a liquid not only scattered but also changed its wavelength. Krishnan observed that the scattered light included new spectral lines in addition to those of the incident light. Raman called this phenomenon ‘modified scattering of light’ and sent his research manuscript to the journal Nature.

To study this scattering in detail, Raman designed a new spectrograph that filtered sunlight using violet and green filters and observed its scattering through different liquids. When violet light was used, they observed a weak greenish glow from the liquid, a signal of new, shifted wavelengths. This was the Raman Scattered Light. Over 60 different liquids showed similar behavior, confirming the reliability of the discovery.

Raman’s findings provided substantial evidence for the quantum nature of light, reinforcing the developing field of quantum physics. On February 28, 1928, this discovery was officially announced and later came to be known as the Raman Effect.

Global Recognition and Accolades

The scientific world hailed Raman’s discovery as revolutionary. In 1930, he was awarded the Nobel Prize in Physics, becoming the first Asian and non-white individual to receive the honor in science. Before that, he had been made a Fellow of the Royal Society in 1924 and was knighted in the same year he won the Nobel Prize, receiving the title Sir C.V. Raman.

The Raman Effect has found applications in several fields such as molecular spectroscopy, chemical analysis, and material science. It is now widely used in laboratories for material characterization and medical diagnostics. In recognition of his monumental contributions, the Indian government declared February 28 as National Science Day.

Raman’s Legacy in Indian Science

Post-Nobel, C.V. Raman continued his journey of scientific excellence in India. He served as the Director of the Indian Institute of Science (IISc), Bangalore, and later established the Raman Research Institute in 1948. Here, he focused on optics and the physics of crystals, mentoring countless young minds along the way.

He was an outspoken advocate for nurturing scientific research in India. Raman believed that science must be accessible, and Indian scientists should develop their unique approaches instead of blindly following the West. His fierce nationalism blended seamlessly with his academic pursuits, making him a towering figure in Indian science.

Why Raman Still Inspires the Next Generation

C.V. Raman’s life teaches children and young adults that curiosity, perseverance, and independent thinking can lead to groundbreaking achievements. Despite facing limited resources and recognition in a colonized nation, he carved his path through sheer dedication and love for knowledge.
