There are certain materials developed in laboratories which have a negative refractive index (Figure). A ray incident from air (medium 1) into such a medium (medium 2) shall follow a path given by:

A)

B)

C)

D)

Correct Answer: A

Solution :

Option [a] is correct

Explanation: The negative refractive index materials are those in which incident materials are those in which incident ray from air (medium 1) to them refract or bends differently or opposite and symmetric to normal to that of positive refractive index medium.
