Question

what are the possible value of refractive index it is greather than 1 or less than 1​

Answer 1

Answer:

GREATER THAN 1 or EQUAL TO

Explanation:

The most medium the value of the index of a refraction is equal to or greater than one however that doesn't mean that less than Unity refraction index values do not occur in factories and research has demonstrated that there exists materials with refractive indexes better or negative
