Changing refractive index. Animation of parallel monochromatic (single colour) light rays passing through a convex lens with the refractive index varying with time. At the start of the animation, the refractive index is one (1) and the light beams pass unaltered through the lens. As the refractive index increases, the light beams are brought to a focus progressively closer to the lens. The refractive index is the speed of light in a vacuum divided by the speed of light in the material.
