Crave the Wave
Sceince Olympid
Term | Definition |
---|---|
crest | highest point of the wave (AKA-Peak) |
trough | lowest point of wave |
rest position | the position the wave would be in I there is no disturbances |
wave length | the distance between two crests or two troughs measured by distance units of the metric system |
amplitude | the distance between a crest or a trough and rest position measured by distance units of the metric system (1/2 of height) |
frequency | the number of times a wave length passes a point in one second and is measured in hz |
period | the time a wave takes to complete a wave length measured in seconds |
p-waves | primary waves (longitudinal waves). the are the first to arrive and they can travel threw liquids |
s-waves | secondary waves (shear waves). transverse waves that are second to arrive. cannot travel threw liquids. |
surface waves | combinations of p and s waves that occur on the surface. they are the slowest waves. |
rayleigh waves | waves that roll in an ocean like motion. |
love waves | waves that move side to side or horizontally. causes the most damage. |
destructive interference | the interference of two waves of equal frequency and facing one another resulting in their cancelation. |
