Calculate the conductivity from the index of refraction and the damping constant for copper (0.14 and 3.35, respectively; measurement at room temperature and λ=0.6 μm). Compare your result with the conductivity of copper (see Appendix 4). You will notice a difference between these conductivities by several orders of magnitude. Why? (Compare only the same units!)

Explanation:

Relation between conductivity, refraction and daming constant is given as:

2nk=б ÷ 2πε₀ν

б=4πε₀nkν

given n=0.14

k=3.35

ν=с/λ =3×10⁸m/s ÷0.6×10⁻⁶m

б=2.6×10²

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
