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 |
