Waves
Diana Liu and Dan Froehlich
Transverse Waves
• displacement perpendicular to wave motion
Longitudinal Waves
• displacement parallel to wave motion
Parts of a wave
trough
crest
Constructive Interference
• When crests and troughs combine, amplitude increasesbigger waves
(IN PHASE)
Destructive Interference
When crests and troughs meet, they cancel each other out smaller waves
OUT OF PHASE
Speed of a Wave
• Velocity-speed at which the wave is traveling• Frequency-number of times a wave passes a
point per second• Wavelength-Length of wave from crest to crest
or trough to trough
Velocity = Frequency x Wavelength
Tsunamis are caused by:
3-LANDSLIDES
• 1-Earthquakes2-VOLCANOES
