A

peak of the wave

22
Q

(8) What is the trough?

A

bottom of the wave

23
Q

(8) What is the wavelength?

A

distance between peaks or troughs

24
Q

(8) What is the wave period?

A

time it takes for a wave to move a instance of one wavelength

25
Q

(8) What is the wave frequency?

A

number of waves passing a fixed point per second

26
Q

(8) What is the amplitude?

A

equal to half the wave height

27
Q

(8) What is wave height?

A

vertical distance from crest to trough

28
Q

What creates a wave?

A

WINDS creates waves in oceans

29
Q

What are other disturbances that cause waves?

A

earthquakes and the gravitational pull of sun and moon

30
Q

What are tsunamis?

A

seismic sea waves created by Earthquakes

31
Q

What are Earthquakes?

A

vertical movement along faults

32
Q

What are tides?

A

long waves created by gravitational pull of the sun and moon

33
Q

What are deep water waves?

A

waves tahat occur in water that is deeper than the wave base, these waves do not “feel” the bottom

34
Q

What is the depth of deep water wave?

A

deeper than halve the wavelength of the wave

35
Q

Depth of a shallow water wave

A

less than L/20

36
Q

What are Shallow water Waves?

A

waves that occur in depths less than 1/20 of wavelength and feel botto

37
Q

What are diurnal tides?

A

occur once daily, have one high and one low tide per day of about equal amp.

38
Q

What is a semidiurnal tide?

A

occur twice daily (2 high and 2 low) about = ample.

39
Q

What is a mixed tide?

A

occur twice daily (2 high and 2 low) but exhibit significantly unequal amplitudes

40
Q

What was a result of the wave lab?
