"WebThe phenomenon of light refraction occurs when light travels from one medium to another. This path alteration occurs at the intersection of two media. When light travels from one medium to another, its speed changes, causing refraction. The phenomenon of refraction explains why lenses can converge or diverge light rays travelling through them.

Web25. apr 2024 · When light moves from one material to another, the change in speed as it slows down or speeds up causes the light rays to bend. This bending is called refraction. Some substances, such as water or certain shapes of glass, can bend light rays so that the white light we normally see is separated into the colors of the rainbow. 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 off different surfaces, it also refracts differently depending on the shape of the material. This can make refraction very useful.
