| Question | Answer |
|---|---|
| diffraction | the bending and spreading of waves |
| refraction | the bending or change in direction of a wave as it passes from one medium to another in which its speed is different |
| reflection | the change in direction of a wave when it bounces off a surface or boundary and returns into the original medium, rather than passing through or being absorbed |
| standing wave | a wave pattern that results when two waves of the same frequency and amplitude travel in opposite directions and interfere with each other |
| constructive wave | a phenomenon that occurs when two or more waves meet at the same point and their crests (high points) and troughs (low points) align in such a way that they combine to produce a wave with greater amplitude than any of the individual waves. |
| destructive wave | occurs when two or more waves meet at the same point and their crests (high points) and troughs (low points) are out of alignment, so that one wave’s crest coincides with another wave’s trough |
| principal of superposition | states that when two or more waves overlap at a point in space, the resulting wave displacement at that point is equal to the sum of the individual wave displacements |
| interference | when two or more waves over lap |
| beats | when two or more waves over lap |
| nodes | specific points along a standing wave where there is no movement |
