Question | Answer |
---|---|
waves carry | energy |
vibrations move ________ from the source | outward |
________ waves can be either transversal or compressional. | mechanical |
_______ waves can only be transversal. | electromagnetic |
the two shapes of waves: | transversal or compressional |
high points in a transversal wave | crest |
low points in a transversal wave | troughs |
distance from one point on a wave to the other nearest wave | wavelength |
# of wavelengths each second | frequency |
half the distance from crest to trough | amplitude |
more energy= | longer its amplitude |
