Transverse Wave | waves that travel in an up and down motion (example: light waves) |
Longitudinal Wave | waves that travel in back and forth in compressional pulses (example: sound waves) |
Mechanical Waves | waves that need a medium to travel (example: sounds waves & earthquake waves) |
Electromagnetic Waves | waves that do not need a medium to travel (example: light waves, x-rays, microwaves) |
Amplitude | wave height |
Wavelength | distance between 2 crests OR 2 troughs |
Frequency | the number of waves that pass by a point each second |
crest | highest point, or peak, of a transverse wave |
trough | lowest point of a transverse wave |
rarefaction | where particles are spread apart in a longitudinal wave |
compression | where particles are bunched together in a longitudinal wave |
