Refraction is when light goes through a prism and all the colors of white light disperse to form a spectrum of seven different colors. Red, orange, yellow, green, blue, indigo, and violet, are the seven colors of the spectrum.
When white light goes through a prism and the light slows down. Different colors in white light have different speeds therefore they split up. Red is the fastest while violet is the slowest. After it exits the prism, the light is still split in seven colors that are mentioned above. A natural example of refraction is a rainbow. The same thing happens in the sky after rain has past. Instead of a prism, a water droplet is used.
When light goes through an object, is bends. As soon as it comes out, it goes back to its normal direction. When light passes through a concave lens, the light diverges on the other side of the lens. Convex lenses cause light to pass through and converge the rays of light on the other side. The convex lens can be used as a magnifying glass, as if the ray were reversed, they would cause the image to get bigger on the lens.
