A flat transparent slab of material with an index of refraction n1 is exposed to the air (n1) and is thus subject to contamination from the air. You?ve been asked to cover the slab with an anti-reflective coating of MgF2 whose index of refraction is n2. What is the smallest thickness of the MgF2 coating that will eliminate reflected light of wavelength λ when the light arrives with an incident angle θ? Please show your work for the following cases.A) If 1 lt; n1 lt; n2.B) If 1 lt; n2 lt; n1.

It means there was a lightning storm in Vatican City that day. Believe it or not, the phenomenon of lightning is fairly well understood, and has been for many centuries. You may wish to ask your primary school teachers more about this. Lightning is no longer considered to be magic as it was back in primitive societies. Supposedly the Vatican gets struck by lightning 40-50 times a year considering it's basically one big lightning rod. You might just be on to something there, genius.
No they would not. Eventually the Shiites will push the Sunni aside and leave the Kurds pretty well alone. The Sunni will eventually keep a low profile but will always resent being dominated by the Shiites. Iraq is a country which needs a strong government and the people will accept it, they do not flinch at police using unusual means to clear cases nor do they consider anyone's rights. They are a proud people who believe more in the common good than an individuals rights or desires. The sooner the US can help form a strong government the better for all concerned. If Iraq was to end up somewhat like Turkey I would call that a huge success but I see an Iraq closely associated with Iran as more likely. The Shiite majority and all but even at that I think that the Iraqi people do not wish to be dominated from Iran. It's certainly going to be an interesting process.
