| 6530383231 | wave | transmits energy but not matter | 0 | |
| 6530398916 | mechanical wave needs a medium to travel through; electromagnetic wave does not | Difference in mechanical wave and electromagnetic wave. | 1 | |
| 6530404088 | transverse wave | particles in the medium travel perpindicular to the direction of energy in what type of wave |  | 2 |
| 6530414828 | longitudinal (compressional) wave | particles in the medium travel parallel to the direction of energy; the medium moves "back AND forth" while the energy only moves forth |  | 3 |
| 6530433815 | amplitude of a wave | Maximum displacement of a medium from the rest position; for transverse wave the "crest or trough"; for a compressional wave "how dense the compressions are"; refers to energy | 4 | |
| 6530453047 | frequency of waves | how many waves per second; high frequency = high pitch, low frequency = low pitch-- evident in the doppler effect | 5 | |
| 6530461175 | doppler effect | an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers. |  | 6 |

| 6531439905 | wave interference (superposition) | the phenomenon that occurs when two waves meet while traveling along the same medium | 25 | |
| 6531447640 | principle of superposition | When 2 or more waves of the same type meet, the total displacement at a point on a wave is the displacements of the individual waves added at that point. |  | 26 |
| 6531469012 | constructive builds (increases amplitude), destructive destroys (decreases amplitude) | compare constructive to destructive interference | 27 | |

| 6533049332 | resonance | Occurs when the frequency of forced vibrations on an object matches the object's natural frequency, and a dramatic increase in amplitude results. A phenomenon that occurs when two objects naturally vibrate at the same frequency |  | 34 |
