Who discovered the sparkling of lights?
VerifiedAnswer: Sir C.V. Raman (scattering of light)
Explanation:
Sir Chandrasekhara Venkata Raman, known as C.V. Raman, was an Indian physicist who made groundbreaking discoveries in the field of light scattering. Born in 1888, he became the first Asian scientist to win the Nobel Prize in Physics in 1930 for his revolutionary work on light behavior.
The "sparkling of lights" refers to the phenomenon where light changes its wavelength when it passes through transparent materials like water, glass, or crystals. This discovery is famously known as the Raman Effect, which Raman discovered on February 28, 1928. This date is now celebrated as National Science Day in India to honor his contribution to science.
When Raman was studying how light behaves when it passes through liquids, he noticed something fascinating. He observed that when a beam of light enters a transparent material, most of it passes through unchanged, but a tiny fraction emerges with a different color or wavelength. This scattered light appeared to "sparkle" with new colors that weren't present in the original light beam.
The scientific explanation behind this sparkling effect is that when light photons interact with molecules in the material, they transfer some energy to the molecules or gain energy from them. This energy exchange causes the scattered light to have a different frequency, creating the sparkling or color-changing effect that Raman observed.
Raman's discovery was remarkable because it provided direct evidence of the quantum nature of light and matter interaction. His work opened up new possibilities in spectroscopy, allowing scientists to identify and study the molecular structure of materials by analyzing how they scatter light. Today, Raman spectroscopy is widely used in chemistry, biology, medicine, and materials science to identify substances and study their properties.
