Wave Interactions
| Term | Definition |
|---|---|
| Reflection | the bouncing back of a wave when it hits a surface through which it cannot pass |
| Law of Reflection | the rule that states that the angle of reflection equals the angle of incidence |
| Refraction | the bending of waves as they enter a new medium causing a change in the speed of the waves |
| Diffraction | the bending and spreading of waves as they move around a barrier or pass through an opening |
| Transparent | transmitting light without interruption or scattering so as to be seen through clearly |
| Translucent | transmitting light with scattering and diffusion so as to be blurry or semitransparent |
| Opaque | allowing no transmission of light energy so as to be impenetrable to sight |
| Absorption | the taking up and storing of energy, such as light or sound, without it being reflected or transmitted |
| Interference | the interaction between two or more waves that meet or intersect |
| Constructive Interference | the interference that occurs when waves combine to make a wave with a larger amplitude |
| Destructive Interference | the interference that occurs when waves combine to make a wave with a smaller amplitude or to cancel the wave |
| Standing Waves | a wave that appears to stand in one place, even though it is really two waves traveling in opposite directions interfering as they pass through each other |
| Resonance | the increase in the amplitude of a vibration that occurs when external vibrations match an object's natural frequency |
