The refractive index of a material with permittivity 16 is given bya)1...
Answer: c
Explanation: The refractive index is the square root of the permittivity. Thus n = √ε. Given that ε = 16, we get refractive index as n = 4. It has no unit.

The refractive index of a material is a measure of how much the speed of light is reduced when it travels through that material compared to its speed in a vacuum. It is a dimensionless quantity and is usually denoted by the symbol 'n'. The refractive index of a material can be calculated using the formula:
n = √(εr)
where εr is the relative permittivity of the material.
Explanation:
Given that the permittivity of the material is 16, we can calculate the refractive index using the formula:
n = √(εr) = √(16) = 4
Hence, the correct answer is option 'C' (4).
Summary:
The refractive index of a material with permittivity 16 is 4.
n = √(εr)
where εr is the relative permittivity of the material.
Explanation:
Given that the permittivity of the material is 16, we can calculate the refractive index using the formula:
n = √(εr) = √(16) = 4
Hence, the correct answer is option 'C' (4).
Summary:
The refractive index of a material with permittivity 16 is 4.
