Accepted Answer

A) True 
 B)False

Question 2

Classification of waves depends on:

Accepted Answer

A)   depth and trough.
B)   wave height and wavelength.
C)   depth and wave height.
D)   wavelength and depth.

Question 3

Celerity is a measure of wavelength and the units are meters.

Accepted Answer

A) True 
 B)False

Question 4

The distance measured from trough to trough of a wave is:

Accepted Answer

A)   the wavelength.
B)   the wave height.
C)   the wave period.
D)   the orbit.

Question 5

The diameter of the orbits of water particles in a deep-water wave is equal to the:

Accepted Answer

A)   wavelength.
B)   wave period.
C)   wave velocity.
D)   wave height.

Question 6

The wavelength of a wave is a measure of the highest part of the wave above the average water level.

Accepted Answer

A) True 
 B)False

Question 7

Constructive Interference in waves can cause:

Accepted Answer

A)   an occasional wave greater than any noted before or after its occurrence.
B)   every other wave to be larger or smaller than those preceding or following.
C)   waves to get smaller within 24 hours.
D)   waves to double in height every 24 hours.

Question 8

Unlike other moving things, wind waves travel over great distances in virtually straight lines. This is physically possible because:

Accepted Answer

A)   while the wave is moving, some water molecules are traveling in closed circles.
B)   the waves don't move as fast as speeding cannon balls, so the Coriolis effect has no influence on them.
C)   waves carry only energy, and energy has no mass, and is therefore not subject to Coriolis deflection.
D)   waves curve one way in the southern hemisphere and the other way in the northern hemisphere. Waves only look like they are coming in a straight line from their point of origin. It's all a gigantic optical illusion, actually.

Question 9

Waves with the greatest propagation rate or celerity:

Accepted Answer

A)   have the longest wavelengths.
B)   occur in shallow water only.
C)   form when the wind is blowing less than 0.5 nautical miles per hour.
D)   have wave periods of less than one second.

Question 10

The energy that causes ocean waves to form is called a disturbing force.

Accepted Answer

A) True 
 B)False

C)   wind waves, tsunami, seiches, tides
D)   tides, seiches, tsunami, wind waves

Question 13

Tsunami or seismic sea waves are generated by:

Accepted Answer

B)   tidal currents in the open sea.
C)   breaking internal waves.
D)   coastal or submarine earthquakes.

Question 14

Waves tend to be parallel to the shore when they break due to the process of:

Accepted Answer

A)   diffraction.
B)   reflection.
C)   refraction.
D)   reaction.

Question 15

The ultimate height of a wind wave will depend on:

Accepted Answer

A)   the fetch.
B)   the length of time the wind blows.
C)   the velocity of the wind.
D)   all of these

Accepted Answer

A)   wind waves
B)   tsunami
C)   seiches
D)   tides

Question 17

For a wave, the longer the wavelength, the faster the wave energy will move through the water.

Accepted Answer

A) True 
 B)False

Question 18

Near shore, if the wave crests are 200 feet apart, the wave will "feel" bottom when the depth is about:

Accepted Answer

A)   20 feet.
B)   50 feet.
C)   100 feet.
D)   200 feet.
