| Question | Answer |
|---|---|
| What is diffraction | the change in direction of a wave when it encounters an obstacle or edge |
| what is refraction | The bending of waves as they pass from one medium to another |
| what is a standing wave | a pattern of vibration that resembles a stationary wave |
| what is reflection | the bouncing back of a wave when it meets a surface or boundary |
| what is constructive int. | interference that increases amplitude |
| what is destructive int. | interference that decreases amplitude |
| what is the principal of superposition | method of adding crests and troughs of interfering waves together to describe a new wave |
| what are beats | sounds produced by the interference of sound waves that are used to tune piano strings |
| what is interference | the combination of two or more waves that result in a single wave |
| what are nodes | points in a standing wave that have no vibration due to destructive interference |
