Sir Chandrasekhara Venkata Raman, discovered on 28 February 1928, that when a beam of coloured light entered a liquid, a fraction of the light scattered was of a different color, dependent on material property. This radiation effect of molecular scattering of light bears the name of ‘Raman Effect’, from which many applications in photonic communications and spectroscopy evolved. The Raman Effect is the process of scattering light particles by molecules of a medium.

convex lenses are used in the human eye to help focus light onto the retina, allowing us to see clearly. The natural lens in the human eye is flexible and can change its shape, allowing it to adjust the focal length and focus on objects at different distances. This process is called accommodation and is essential for clear vision.

soybeans contain the highest amount of protein. Soybeans are a complete protein, meaning they provide all nine essential amino acids that the human body cannot produce on its own. Other high-protein vegetables include lentils, chickpeas, black beans, and green peas. Including a variety of these plant-based protein sources in your diet can contribute significantly to your protein intake.
