| Term | Definition |
|---|---|
| Wave | A traveling disturbance that carries energy from one place to another |
| Mechanical waves are created when a source of energy causes a medium to | move |
| Speed = | wavelength multiplied by frequency |
| Refraction | The bending of waves due to a change in speed |
| Diffraction | The bending of waves around an obstacle |
| Interference | The interaction between two waves that meet |
| Constructive Interference | When waves combine to make a wave with larger amplitude |
| Standing wave | When an incoming wave combines with a reflected wave in such a way that the combined wave appear to be standing still |
| Resonant Frequency | When vibration travels through an object at the same speed of the object it travels through |
| the energy passes from one particle to another | A wave travels through a medium because |
| How they move | A mechanical wave is classified according to |
| Hertz | Frequency is measured in |
| Reflection | When a wave hits a surface and bounces off of that surface |
| Destructive Interference | When waves combine to produce a smaller or zero- amplitude wave |
| Light travels faster then sound | The reason for why you see lightning before hearing thunder |
| Longitudinal Wave | Compression and rarefaction are characteristics of a |
| Wavelength | The distance between two consecutive crests |
| Transverse Wave | Where the motion of the medium of the wave is traveling at a right angle to the motion of the wave |
| Frequency | Waves / Seconds |
| Compression | Space where the particles are crowded together |
| Rarefaction | Space between compression |
