Asked by Iza

I'm supposed to fill in a table. The angle of incedence in air is given (starting with zero degrees and then at 10, 20, 30, 40, 50 and 60 degrees. Using the sin function on my calculator, I'm supposed to figure out the angle of refraction in an acrylic block.

Can anyone help me?

Pretty much nothing. I'm really lost. I don't even know how to use my calculator with that SIN function.
