Internal wave quiz: 3 questions
Three questions on the Internal wave card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
If the ______ changes continuously, the waves can propagate vertically as well as horizontally through the fluid.
Answer
density. If the density changes continuously, the waves can propagate vertically as well as horizontally through the fluid. From the Internal wave article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Richard Lietz. Richard Lietz 79 · Matthew Meselson 71 · Internal wave 67 · Fulton, Mississippi 61 ATK in WikiCards.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- To exist, the fluid must be stratified: the density must change with depth/height due to changes, for example, in temperature and/or salinity.
- If the density changes over a small vertical distance, the waves propagate horizontally like surface waves, but do so at slower speeds as determined by the density difference of the fluid below and above the interface.
- If the density changes continuously, the waves can propagate vertically as well as horizontally through the fluid.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Internal wave article was read about 9,700 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 67 and blocks with 51: each hit it takes is cut by 20 %.
How to get Internal wave
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
