WebThe dielectric constant - also called the relative permittivity indicates how easily a material can become polarized by imposition of an electric field on an insulator. Relative permittivity is the ratio of "the permittivity of a substance to the permittivity of space or vacuum ". ε0 = permittivity of vacuum or free space (8.854187817 10-12 C2 ... WebThe index of refraction ( n) of any material is the ratio of the speed of light in vacuum, c = 2.99792458 × 10 8 m / s, to the speed of light in that material. n = c v. where v is the speed of light in the material. Notice that because we divide a velocity by a velocity here, the result is unitless. The index of refraction, n, is unitless. phlebotomist salary 2023
