Refraction of light through glass bar- How Light Bends Explained (3D Animation)

This fascinating demonstration shows the science of refraction, where light bends as it passes from one medium to another. It’s a simple phenomenon that reveals the hidden complexity of the natural world around us. What looks like a magic trick is actually pure physics in action. Refraction explains why objects appear bent in water, why lenses can focus light, and even why rainbows form in the sky. It’s a principle woven into daily life, often unnoticed yet profoundly impactful. Understanding it
