Snell's Law
sin tetha1/v1 = sin tetha2/v2
n1 = c/v1
n1 . sin tetha 1 = n2 . sin tetha 2
The Attempt at a Solution
I try to make triangle out of line PO, so that it will have correlation to tetha, since o = center, then let's say there's point C at circle circumference. then POC is isosceles triangle.
PC^2 = PO^2 + CO^2 - 2PO.CO.cos tetha
PC^2 = 2R^2 - 2R^2 cos tetha
PC^2 = 2R^2 ( 1 - cos tetha)
n value for air = 1.00 ? but I cannot find the correlation tetha to n, and especially h...?
