Physics 17.1 and 17.2
Answer | |
---|---|
medium | the material through which a wave travels |
crest | the highest point above the wave above rest position |
through | the lowest point below the rest position |
transverse wave | a wave that causes the medium to vibrate at right angles to the direction in which the wave travels |
compression | an area where particles in a medium are spaced close together |
longitudinal wave | a wave in which the vibration of the medium is parallel to the direction the wave travels |
surface wave | a wave that travels along a surface separating two media |
periodic motion | any motion that repeats at regular time intervals |
period | the time required for one cycle |
cycle | a complete motion that returns to its starting point |
frequency | the number of complete cycles in a given time |
hertz | frequency is measured in cycles per second |
wavelength | the distance between a point on one wave and the same point on the next cycle wave |
amplitude | the maximum displacement of the medium from its rest position |
rarefraction | an area where the particles in a medium are spread out |
