Vocab
any disturbance that transfers energy through matter or empty space.
wave
Top part of the wave
crest
Equation for wave speed
Wave speed= wavelength x frequency
What is the primary factor that determines the size of ocean waves?
wind speed
Describe one factor that causes water displacement/ a tsunami.
Earthquake
Volcanoes
Landslide
Meteorite/ Asteriod
a disturbance that transfers energy through ocean water.
Bottom part of the wave
trough
The speed of a wave is 65 m/sec. If the wavelength of the wave is 0.8 meters, what is the frequency of the wave?
81.25 Hz
What distinguishes a tsunami from other types of ocean waves?
A tsunami forms when a large volume of water is suddenly displaced up or down.
Explain how a wave transfers energy through ocean water.
Wind blows and energy is transferred in the form of waves. Water created ripples. Wave does not carry water but rather transmits energy. This transfer of energy is how waves move through the ocean.
a series of waves that form when a large volume of ocean water is suddenly moved up or down.
tsunami
Distance between one crest and another/ one trough and another
wavelength
A wave with a frequency of 500 Hz is traveling at a speed of 200 m/s. What is the wavelength?
0.4 m
Draw an example of a wave. Label the crest and trough, amplitude and wavelength.
on board
Why is it crucial to understand ocean waves?
Weather forecasting
climate change
plate tectonic movement
carries energy through matter, such as water.
mechanical wave
a measurement of how much time it takes for a wave to pass the fixed point.
wave period
A wave with a frequency of 14 Hz has a wavelength of 3 meters. At what speed will this wave travel?
42 m/s
describe the motion of water particles due to the action of waves
They rise and fall in a circular motion.
As a wave moves into shallow water, what causes the top of the wave to break and topple over?
Contact with the ocean floor causes the wave to slow down and eventually break.
