Longitudinal wave | Particles move back and forth in the same direction that the wave travels. |
Compression | Engrey is transfred from one end of the spring toy to another. |
Rarefraction | When you spread the coils apart. |
Transverse wave | Wave,the spring coils move up and down. |
Mechanical waves | Waves that require a meduim. |
Amplitude | is a measure of how for particles in the meduim move from their rest postion. |
Wavelength | Is defined as the distance from any ponit on a wave to the next identical ponit on the same wave. |
Frequency | Is the number of waves that pass a ponit in a given amount of time usually one second. |
Hertz | One hertz is equal to one wavelength per second. |
Wave speed | The speed that waves travel. |
Power | In a phyicial amount energy put out of or produced in agiven amount of time. |
Work | Activity in which one exerts strength or faclties to do or perform something. |
