Most materials have the refractive index, n>1 . So, when a light ray from air enters a naturally occurring material, then by Snell's law, ₁ ₂ = n₂ n₁ , it is understood that the refracted ray bends towards the normal. But it never emerges on the same side of the normal as the incident ray. According to electromagnetism, the refractive index of the medium is given by the relation, n =c / v= _ r _ r , where c is the sp

Correct answer

2

Step-by-step solution

Let n₁= refractive index of air and n₂= refractive index of meta material which is negative From Snell's law, n₂ n₁ = ₁ ₂ n₂ negative ₂ isalso negative hence graph (c) is correct.
