Waves
Term | Definition |
---|---|
amplitude | the maximum distance the wave vibrates from its rest position (height) Measures energy of wave |
compression | The region in a compression wave where the medium becomes crowded together and becomes more dense |
crest | highest point of a transverse wave |
frequency | the number of wavelengths that pass a fixed point each second |
longitudinal Wave | same as a compression wave |
mechanical wave | a wave that requires a medium |
medium | substance through which a wave travels |
rarefaction | less dense region of a compression wave |
transverse wave | a wave in which the medium(material) moves back and forth at right angles to the direction of the wave |
trough | the lowest point of a transverse wave |
wave | rhythmic disturbance that transmits energy through matter or space |
wave length | the distance between crest to crest or trough to trough |
compression wave | a wave in which the medium (matter) moves back and forth in the same direction as the wave |
reflection | bouncing back of a wave as it meets a boundary or surface |
refraction | bending of waves as they pass from one medium to another |
diffraction | bending of waves as they go around and object or through an opening |
