Refraction by … scorbunny grookey and sobbleWebIndex of Refraction is the speed of light in a vacuum divided by the speed of light in a given material. The resulting number (1.5, 1.6, 1.67, 1.74) is referred to as the “index.”. The higher the number, the more light is slowed down or bent. This means high-index lenses bend light at steeper angles than standard-index, hard resin lenses. scorbunny halloween costume
