Question

A hypothetical material has a relative permeability and relative permittivity of 3.0 and 4.0, respectively.

(a) What is the speed of light in this material?

(b) What is the index of refraction of the material?

Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.
