i=angle of incidence, r= angle of refraction =90°, μ=refractive index.
Snell's law: sini/sin90°=μ, sini=μsin90°=μ, i=sin⁻¹μ.

Measuring angles from the traditional: If the attitude of prevalence is ninety ranges the ray can not hit the replicate, so the question has no meaning. in case you degree from the exterior: The ray hits immediately on, and is pondered alongside an identical course.
