| Question | Answer |
|---|---|
| what wave moves up and down | transverse wave |
| what wave moves side to side | longitudinal wave |
| the highest point of a transverse wave is called... | crest |
| the lowest point of a transverse wave is called... | trough |
| how is the amplitude measured in a transverse wave | from the origin (or mid-point) to the crest or origin to the trough |
| what is the frequency | the number of waves produced by a source each second |
| The point where particles push together is called... | compression |
| The point where particles spread apart is called | rarefraction |
| how is the frequency measured? (longitudinal wave) | compression to compression or rarefraction to rarefraction |
| how is frequency measured? (transverse wave) | crest to crest or trough to trough |
| what do transverse waves carry? | light energy |
| what do longitudinal waves carry? | sound energy |
