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. Web1. aug 2024 · Those are two separate ways of looking at the refraction of light through the lens. In reality you are correct. Rays passing through the physical lens are refracted at both front and rear faces.
