SUMMARY
The minimum value of the index of refraction (n) is definitively 1, as it represents the ratio of the speed of light in a vacuum (c) to the speed of light in a material (v). The equation governing this relationship is n = c / v, where light always travels slower in any medium compared to a vacuum. Therefore, the index of refraction cannot be less than 1, as indicated by the options presented: A (between 0 and 1), B (+1), C (-1), and D (0). The correct answer is B (+1), confirming that the index of refraction is always equal to or greater than 1.
