Question

Rogue waves are defined as waves that are at least ___ times higher than the significant wave height

O a. 2
O b. 4
O c. 6
O d. 10

Answer 1

Rogue waves are at least twice the significant wave height, which means the correct choice is (a) 2 times higher. Wave height is twice the amplitude, so a wave with 1 m amplitude has a 2 m height.

Step-by-step explanation:

Rogue waves are defined as waves that are at least twice as high as the significant wave height. Therefore, the correct answer to the question is a. 2 times higher.

Now, let's tackle the provided GRASP CHECK sections for further clarification. If you are on a boat in the trough of a wave and the wave amplitude is 1 m, the wave height from your position would be 2 m, because the height of a wave is considered the full distance from trough to crest, which is twice the amplitude.

Additionally, if the crest of a wave measures 2 m above still water, the amplitude of the wave is 1 m. Amplitude is defined as the distance from the still water level (the midpoint) to the crest, so it's half the total height of the wave.
