NEETPhysicsGeometrical OpticsMCQ+4 / −1

ϵ0\epsilon_0ϵ0​ and μ0\mu_0μ0​ are the electric permittivity and magnetic permeability of free space respectively. If the corresponding quantities of a medium are 2 ϵ02 ~\epsilon_02 ϵ0​ and 1.5 μ01.5 ~\mu_01.5 μ0​ respectively, the refractive index of the medium will nearly be :

  1. A
    2\sqrt{2}2​
  2. B
    3\sqrt{3}3​

Correct answer: B

$$\mu=\frac{C}{\mathrm{~V}}=\frac{\frac{1}{\sqrt{\mu_0 \in_0}}}{\frac{1}{\sqrt{1.5 \mu_0 \times 2 \epsilon_0}}}=\sqrt{3}$$
