Calculate the angle of refraction for a substance that has a critical angle of 50.5 degrees when that substance is in the air.

2. Relevant 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?

3. The attempt at a solution
