The refractive index of a medium with permittivity of 2 and permeabili...
Answer: b
Explanation: The refractive index is given by n = c √(με), where c is the speed of light. Given that relative permittivity and relative permeability are 2 and 3 respectively. Thus n = 3 x 108√(2 x 4π x 10-7 x 3 x 8.854 x 10-12) = 2.45.

The refractive index of a medium with permittivity of 2 and permeabili...
Given: Permittivity (ε) = 2, Permeability (μ) = 3
We know that the refractive index of a medium is given by:
n = √(μ/ε)
Substituting the given values, we get:
n = √(3/2) = 1.732√2
Simplifying further, we get:
n ≈ 2.45
Therefore, the correct answer is option B.
Explanation:
Refractive index is a measure of how much a ray of light bends when it passes through a medium. It is determined by the optical properties of the medium, such as its permittivity and permeability.
In this question, we are given the values of permittivity and permeability of a medium, and we are asked to find its refractive index. To do this, we use the formula n = √(μ/ε), where n is the refractive index, μ is the permeability, and ε is the permittivity.
Substituting the given values, we get n = √(3/2). Simplifying this expression, we get n ≈ 2.45. Therefore, the correct answer is option B.
