Question

The relative permeability of glass is 3/8 and the dielectric constant of glass is 8. the refractive index of glass is

1) 1.5
2) 1,1414
3) 1.732
4) 1.6

Answer 1

The refractive index of glass, with a relative permeability of 3/8 and dielectric constant of 8, is calculated using the formula n = sqrt(epsilon_r * mu_r) resulting in an index of about 1.732.

option c is the correct

Step-by-step explanation:

The refractive index of a material is a measure of how much it reduces the speed of light, compared to the speed of light in a vacuum. For glass, we need to relate its given relative permeability and dielectric constant to its refractive index. According to the formula for the refractive index n, where n = sqrt(\epsilon_r \mu_r), with \epsilon_r being the dielectric constant and \mu_r the relative permeability, we can calculate the refractive index for glass. Given that the dielectric constant of glass is 8 and the relative permeability is 3/8, we calculate n as follows:

n = sqrt(8 \cdot \frac{3}{8}) = sqrt(3) \approx 1.732.

Therefore, the refractive index of glass is approximately 1.732.
