Homework Statement
Calculate the angle of refraction for a substance that has a critical angle of 50.5 degrees when that substance is in the air.
Homework Equations
Apparently the equation I need is:
ni *• sine() = nr • sine ()
My problem is, I have no idea how to use this formula or if it's even the right one - my teacher told me to write it down with no explanation.
Please help me, I just need to know what the equation actually tells me - where I am supposed to input data?
