Snell's law says
n1sin(theta1) = n2sin(theta2)
The angle of refraction theta2 can be greater or less than the angle of incidence theta1. That's fairly obvious.
My question is if theta2 = theta1 then we don't have an interface (because n1 = n2) so the light is still in the same medium, and there is nothing to talk about?
Is there a case where there is an interface and theta2 = theta1 ?
