Light travels from a medium of refractive index µ1 to another of refractive index µ2 (µ1 > µ2). For total internal reflection

Light travels from a medium of refractive index µ₁ to another of refractive index µ₂ (µ₁ > µ₂). For total internal reflection of light, which is NOT true?

(A) Light must travel from medium of refractive index µ₁ to µ₂.

(B) Angle of incidence must be greater than the critical angle.

(C) There is no refraction of light.

(D) Light must travel from the medium of refractive index µ₂ to µ₁.
