MCQ (Single Correct Answer)

-1

Choose the correct statement.

The speed of light in the meta-material is $$v = c|n|$$.

The speed of light in the meta-material is $$v = {c \over {|n|}}$$.

The speed of light in the meta-material is v = c.

The wavelength of the light in the meta-material ($$\lambda$$_m) is given by $$\lambda$$_m = $$\lambda$$_air | n |.
