    If the angle of incidence (θ₁) is greater than the critical angle (θ_c), then total internal reflection occurs.

    (2bii) Snell’s law states that the ratio of the sine of the angle of incidence (θ₁) to the sine of the angle of refraction (θ₂) is equal to the ratio of the velocities of light in the two media, which is also equal to the inverse ratio of their refractive indices.
