Question
There are certain material developed in laboratories which have a negative refractive index (Fig). A ray incident from air (medium 1) into such a medium (medium 2) shall follow a path given by:
✓
Answer
Solution:
The materials with negative refractive index responds to Snell’s law just opposite way. If incident ray from air (Medium 1) incident on those material, the ray refract or bend same side of the normal as in option (a).
