Fresnel equations, an Uncommon card
The Fresnel equations describe the reflection and transmission of light when incident on an interface between different optical media.

The facts on the card
The card carries these facts from its Wikipedia article.
- They were deduced by French engineer and physicist Augustin-Jean Fresnel who was the first to understand that light is a transverse wave, when no one realized that the waves were electric and magnetic fields.
- For the first time, polarization could be understood quantitatively, as Fresnel's equations correctly predicted the differing behaviour of waves of the s and p polarizations incident upon a material interface.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Fresnel equations article was read about 120,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 80 and blocks with 72: each hit it takes is cut by 29 %.
How to get Fresnel equations
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.
