| A | B |
| This occurs when light strides an object and bounces off | reflection |
| This means that light cannot be transmitted through an object | opaque |
| Light does this when it refracts throug a prism | changes speed |
| Caused when light refracts through air layer of different densities | mirage |
| A material that allows 'some' light to pass through | translucent |
| Transmits almost all the light that strikes it. | transparent |
| The angle of incident = angle of reflection | Law of Reflection |
| Reflection that doesn't produce a clear image | diffuse |
| Reflection that will produce a sharp image | regular |
| A property of a material that relates how much light slows down | Index of Refraction |
| Why colors seperate in a prism. | the different frequencies of light bend at different rates |
