Prisms are beautiful crystals that make ordinary light look like a rainbow, but how do they work? Prisms work by reflecting light. Light enters the prism from the air changing speeds as it enters. This change in speed causes the light to refract bending at different angles. Then when the light exits the prism, its does so at different angles making different colors.
