Wave 6th
Amplitude | half the height of the wave from the crest to the trough |
crest | top of wave |
frequency | number of waves during a set time period |
transverse wave | matter in the medium moves at a right angle to the direction of the wave |
trough | lowest part of the wave |
wave length | distance from one point on a wave tot he identical point on the next wave |
longitudinal wave | energy moves forward along the wave |
vibrations | back and forth movement of matter |
pitch | perceived frequency of a sound |
decibel | unit used to measure loudness |
hertz | unit used to measure frequency |
compression | compressed part of the longitudinal wave |
intereference | addition and subtraction of wave crests and troughs |
medium | material needed to transfer sound |
rarefaction | expanded part of longitudinal wave |
displacement | difference in current position and previous position |
