Science waves unit
Test February 10th
| Question | Answer |
|---|---|
| Wave | a disturbance that carries Energy as it travels |
| Medium | what a wave travels through |
| Mechanical Wave | a wave that requires a medium to travel through (can’t travel through a vacuum like space) |
| 2 Types of Mechanical Wave | Transverse Longitudinal (compressional) |
| Transverse Wave | a wave that moves in a perpendicular (up and down) direction |
| Crest | high points |
| Trough | low points |
| Amplitude | distance between the crest/trough and the resting point |
| Wavelength | distance between 2 crests or 2 troughs |
| As amplitude increases, what do you think also increases? | ENERGY!! |
| Longitudinal (Compressional) Wave | a wave that travels in the Same direction as the vibrations that produce it |
| Frequency | the number of waves that pass a given point in a certain amount of time |
| Transverse Wave measurement | - measured crest to crest or trough to trough |
| Longitudinal Wave measurement | - distance from one compression to the next compression |
