Question | Answer |
---|---|
wave | disturbance that transfers energy |
mechanical wave | travels through a medium |
medium | what a wave travels through |
electromagnetic wave | can travel without a medium |
transverse wave | travels perpendicular to direction of sources motion |
amplitude | distance (height) between crest and rest position |
longitudinal wave | travel same direction as vibrations |
rope | example of transverse wave |
slinky | example of longitudinal wave |
surface wave | combination of transverse and longitudinal waves |
wavelength | distance crest to crest, or compression to compression |
frequency | number of times a wave repeats in given time |
crest | top of wave |
trough | bottom of wave |
compression | waves crowded together |
rarefaction | waves spread apart |
