| photon | a bundle of energy that is released when an atom loses some energy |
| frequency | the number of waves (crests or troughs) that pass a point given amount of time |
| amplitude | the distance between a wave's mid-point and its crest or trough |
| transverse wave | a wave in which the crests and troughs move at right angles to the direction of the wave's travel |
| convex mirror | a mirror whose center section curves toward an object |
| concave mirror | a mirror whose center section curves away from an object |
| refraction | the bending of a light wave as it moves from one material to another |
| focal point | the point which light rays meet when reflected or refracted |
| laser light | light of a single wavelength with all the waves lined up |
| 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 |
| transparent | allows light to pass through so that objects on the other side can be seen |
| music | pleasant sound with regular wave patterns |
| noise | sound wiht no regular wave pattern |
| octave | a musical sequence in which the top note has twice the frequency of the bottom note |
| radar waves | one of the types of wave that come from the sun |
| microwaves | An electromagnetic wave with a wavelength between that of infrared and short waves |
| Doppler effect | A change in the observed frequency of a wave |
