Waves Review
review of different waves and sound
| Question | Answer |
|---|---|
| Doppler effect | an observed change in frequency when either the sound source or observer moves |
| EM | wave that does not require a medium |
| surface | wave with perpendicular and parallel particles |
| longitudinal | wave with parallel particles |
| transverse | wave with perpendicular particles |
| medium | the matter that waves move through |
| energy | this is transferred by a wave |
| rarefaction | the less dense area of a longitudinal wave |
| compression | the most dense area of a longitudinal wave |
| mechanical | wave that requires a medium |
| Hertz | SI unit for frequency |
| speed of light | all EM waves travel at this speed |
| period | time it takes to complete 1 wave cycle |
| frequency | # of wave cycles completed in a unit of time |
