Refractive index of medium A with respect to medium B is given by:

Question

Accepted Answer

D. n_AB = speed in B / speed in A

1. Relative refractive index of A w.r.t. B equals v_B/v_A.
2. This follows from Snell's law: n₁ sin θ₁ = n₂ sin θ₂.
3. When A is denser than B, n_AB > 1.

Answer

n_AB = wavelength in A × wavelength in B

Answer

n_AB = speed in A / speed in B

Answer

n_AB = sin(i in A) / sin(r in A)
