Refraction straw in water in a glass

WebStraight things often look bent when they stand in water. The science behind this illusion is called refraction. Light rays usually travel in straight lines, but when they pass from one material to another they can bend. This happens because light travels at different speeds in different materials. WebThis "refraction" of light is the reason a straw in water looks bent or broken and why objects viewed through a glass bottle appear distorted. In the same way light reflects differently …
