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 |
