Find the relative permittivity of the medium having a refractive index...
Answer: b
Explanation: The refractive index is the square root of the relative permittivity. It is given by n = √εr. To get εr, put n = 1.6. We get εr = n2 = 1.62 = 2.56(no unit).

Find the relative permittivity of the medium having a refractive index...
Relative permittivity and refractive index are related through the formula:
n = sqrt(εᵣ)
where n is the refractive index and εᵣ is the relative permittivity.
To find the relative permittivity, we need to square both sides of the equation and isolate εᵣ:
n² = εᵣ
Now we can substitute the given refractive index of 1.6 into the equation to get:
εᵣ = (1.6)² = 2.56
Therefore, the relative permittivity of the medium is 2.56.
Answer: (B) 2.56
n = sqrt(εᵣ)
where n is the refractive index and εᵣ is the relative permittivity.
To find the relative permittivity, we need to square both sides of the equation and isolate εᵣ:
n² = εᵣ
Now we can substitute the given refractive index of 1.6 into the equation to get:
εᵣ = (1.6)² = 2.56
Therefore, the relative permittivity of the medium is 2.56.
Answer: (B) 2.56
