Question

Choose the correct statement

The wavelength of the light in the meta-material ( $λ$ _m) is given by $λ$ _m = $λ$ _air |n|, where $λ$ _air is the wavelength of the light in air

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

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

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

Since the physical laws remain the same, the speed of light is lesser in meta-materials.

So v = $\frac{c}{| n |}$

1 sin $θ$ ₁ = n sin $θ$ ₂. Since n is negative, $θ$ ₂ is also negative. So the ray rotates and goes on the opposite side of the normal.
