₀ and ₀ are the electric permittivity and magnetic permeability of free space respectively. If the corresponding quantities of a medium are 2 ₀ and 1.5 ₀ respectively, the refractive index of the medium will nearly be

Options

  1. A3
  2. B2
  3. C2
  4. D3

Correct answer

D. 3

Step-by-step solution

We know aligned & Refractive index = ₀ ₀ & = (1.5) ₀(2) ₀ ₀ ₀ & = 3 aligned
