| Refraction can separate white light into what? | different colors |
| Whether an object is transparent, translucent, or opaque is determined by its ability to do what? | transmit light |
| The mixing of colors of light together is called | color addition |
| When white light is refracted, the amount that the light bends depends on what? | The wavelength |

| The membrane that protects the eye and through which light is refracted is the | cornea |
| The surface of a concave mirror | curves inward |
