Yes, n = 1 / sin C is derived from Snell's Law. We can't write n = sin C / sin 90 ∘ because n > 1 is refractive index of denser medium (in which light ray is incident) w.r.t. rarer medium (in which light ray refracted). Mathematically also, C = sin − 1 ( n) becomes undefined therefore n ≠ sin C. Derivation: Let ∠ i be the angle of ...
