Refraction | the bending of a light wave as it moves from one material to another |
Focal point | the point at which light rays meet when reflected or refracted |

Opaque | does not allow light to pass through |
Transparent | allows light to pass through so that objects on the other side can be seen |
Compressional wave | wave in which matter vibrates in the same direction as the energy waves traveling through it |
Intensity | a measure of the amount of energy in a wave |
Sonar | A device which uses sound waves to measure distance |
