Question:

Help!! Physics 2 problem!! A flat transparent slab of material with an index of refraction n1?

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.

Thumbs up to Fish Steel. Walmart IS probably the cheapest place you would find one..but think about this: 1. Walmart is owned by China. Every time you buy something from Walmart your helping the Chinese conquer America. (Sounds crazy but it's true!) Are you an American? Go to your local Mom Pop bait tackle in your area and buy it there! It might cost $4-$5 more but at least your helping the American economy and not the Chinese economy. And your local B T will provide you more INFORMATION than ANY Walmart ever could! And good info is the key to catching everything..
