Diffraction | The change in direction of a wave when it encounters an obstacle or edge |
Refraction | The bending of waves as they pass from one medium to another at an angle |
Standing Wave | A pattern of vibration that resembles a stationary wave |
Reflection | The bouncing back of a wave when it meets a surface or boundry |
Constructive Interference | Interference that increases amplitude |
Destructive Interference | Interference that decreases amplitude |
Principle of Superposition | Method of adding crests and troughs of interfering waves together to describe a new wave |
Beats | Sounds produced by the interference of sound waves that are used to tune piano strings |
Interference | The combination of two or more waves that results in a single wave |
Nodes | Points in a standing wave that have no vibration due to destructive interference |
